RSS FEED IDEMS: Technical Interview Questions
- Java Swing interview questions
1) Can a class be it’s own event handler? Explain how to implement this.
Ans: Sure. an example could be a class that extends Jbutton and implements ActionListener. In the actionPerformed method, put the code to perform when the button is pressed.
2) Why does JComponent have add() and remove() methods but Component does not?
Ans: because JComponent is a subclass of Container, and can contain other components and jcomponents.
3) How would you create a button with rounded edges?
Ans: there’s 2 ways. The first thing is to know that a JButton’s edges are drawn by a Border. so you can override the Button’s paintComponent(Graphics) method and draw a circle or rounded rectangle (whatever), and turn off the border. Or you can create a custom border that draws a circle or rounded rectangle around any component and set the button’s border to it.
4) If I wanted to use a SolarisUI for just a JTabbedPane, and the Metal UI for everything else, how would I do that?
Ans: in the UIDefaults table, override the entry for tabbed pane and put in the SolarisUI delegate.
5) What is the difference between the ‘Font’ and ‘FontMetrics’ class?
Ans: The Font Class is used to render ‘glyphs’ - the characters you see on the screen. FontMetrics encapsulates information about a specific font on a specific Graphics object. (width of the characters, ascent, descent)
6) What class is at the top of the AWT event hierarchy?
Ans: java.awt.AWTEvent. if they say java.awt.Event, they haven’t dealt with swing or AWT in a while.
7) Explain how to render an HTML page using only Swing.
Ans: Use a JEditorPane or JTextPane and set it with an HTMLEditorKit, then load the text into the pane.
8) How would you detect a keypress in a JComboBox?
Ans: This is a trick. most people would say ‘add a KeyListener to the JComboBox’ - but the right answer is ‘add a KeyListener to the JComboBox’s editor component.’
9) Why should the implementation of any Swing callback (like a listener) execute quickly?
Ans: Because callbacks are invoked by the event dispatch thread which will be blocked processing other events for as long as your method takes to execute.
10) In what context should the value of Swing components be updated directly?
Ans: Swing components should be updated directly only in the context of callback methods invoked from the event dispatch thread. Any other context is not thread safe.
11) Why would you use SwingUtilities.invokeAndWait or SwingUtilities.invokeLater?
Ans: I want to update a Swing component but I’m not in a callback. If I want the update to happen immediately (perhaps for a progress bar component) then I’d use invokeAndWait. If I don’t care when the update occurs, I’d use invokeLater.
12) If your UI seems to freeze periodically, what might be a likely reason?
Ans: A callback implementation like ActionListener.actionPerformed or MouseListener.mouseClicked is taking a long time to execute thereby blocking the event dispatch thread from processing other UI events.
13) Which Swing methods are thread-safe?
Ans: The only thread-safe methods are repaint(), revalidate(), and invalidate()
14) Why won’t the JVM terminate when I close all the application windows?
Ans: The AWT event dispatcher thread is not a daemon thread. You must explicitly call System.exit to terminate the JVM.

Infosys paper : 5th November-2006 .venue: sydhenam college ,mumbai.
Hello friends .i am mayur,an M.Sc graduate(2006 fresher) .I had appeared for the test and would like to share my experience and give u a brief idea about the test. By now everyone must be aware that the paper pattern has changed. yes, its true. But don’t FRET. It’s not that difficult . it’ s CAT Pattern. so one just needs 2 change ones mindset from puzzles 2 that of CAT. And then it woud be easy to crack it. one was supposed to circle the right answer and also was expected 2 show the working in the rough sheet provided. so please show the working wherever possible.
The aptitude test consisted of 2 sections:
1)analytical thinking/logical reasoning –30Q( 45min)
2)English - 40Q(30 min).
analytical thinking/logical reasoning:
Ques(1-5):(based on arrangements) There are 5 books of english,biology ,chemistry,physics,Sanskrit,economics.the order in which they are arranged with respect to the other and the page nos are given.and then 5 question followed each havin 4 options each.
Ques(6-10):(visual reasoning)4 out of the given 5 figures are similar in certain way. find the one which is odd.
Ques(11-15):(data sufficiency)Each question is followed by two statement,1 and 2.answer each question using the following instructions:
Choose 1 if the queston can be answered by using one of the statement alone ,but cannot be answered using the other statement alone.
Choose 2 if the question can be answerd by using either of the statement alone.
Choose 3 if the question can be answered by using both of the statements together ,but cannot be answered using either of the statement aone.
Choose 4 if the question cannot be answered even by using both the statements together.
Ques(16-20)(data interpretation)some statistics of population .the mortality rate, the birthrate etc.
Ques(21-25)(based on family tree).some relations given.and then followed by 5 questions each havin 4 options.
Quest(26-30)(verbal reasoning)Choose the set of three statement that make a logical sequence from the given four.

2)fill in the blanks with the appropriate words.
English section was pretty tough since all options were quite close and lot many questions were asked.
Interview:
I had 2 rounds of interview .first panel consisted of 3 ppl.it was a hr interview,no technical questions asked. . tell me somethinh abt urself. hobbies. why u want 2 get into software? wht are your personal goals in life. abt the project. extra curricular activities.
They just want to find out whether u are a team player ,a team leader.ur lernability,ur communication skills.i was not asked any puzzle.
I have tried to give u an idea of how the new pattern is. I want 2 reiterate what I said earlier ,just remember its not difficult just one needs 2 change ones mindset or else have a flexible one. don’t expect only puzzles . just be ready 2 face whatever u get and then u would be able to crack it.

Sapient Test Paper ON 19/05/06 Banglore
Hello
I had attended sapient test on 19/05/2006 in Bangalore for 1+ year experience
The test paper
We had two parts partA and part B----
PartA: spend 40 min here
We are developing a website for a plane Reservation, once the user enters the from and
To Destination and the Date.The web site should display all the planes on that day in a
list of 10 planes at a time. The details are given by a node []
Each node gives following details
Node []
Flight Name ()
Flight Time ()
FromToDestination ()
isDirect ()
isStartOver ()
Flight Rate ()
Assume all the data are in arrays, the following conditions as to be followed while displaying
the list of flights
1. the flights should be displayed in the ascending order of rate
2. If price are equal then it should display direct flight first
3. If there are more than one flight with same rate and they are direct then the flight which
starts early will take the priority
4. If there are more flight at the same time than the one with ascending order of Organization
will take priority
5. I forgot one more condition
Write the method for all the process, no need to write exact code write all the methods and
business application
PartB: spend 20 min here(its very easy)
This is an application which converts an English language to piniac language which is
understood by small kids The software program is written and executed ,the program as to
add 'ay' to all the words starting with vowel at the end, if the word is starting with consents
peal the first letter and add at the end along with'ay'
The actual output
Erehay isay aay ayway ofay onvertingcay englishay toay iniacpay
Output of our software
Erehay isway away ayway ofway onvertingcay englishway toay iniacpay
Assume all the methods are ready and working don't change the logic or add additional
characteristic
Write the comments for the following code, and check for errors and bugs, we are
looking for your error correcting skills and code knowledge
Class piniac
{
is Vowel(char first)
{I'm not able to recall the exact code but its very easy with simple
methods}
addletter (first,' a');
addletter (first.'y');
addletter (first,'\0');
}

Question 1:
There is a company who has a number of employees. Every employee except the CEO can report to only one boss.
The class structure is given as
Employee :
:name,salary,isBoss
methods:getName,getSalary
Each employees cost to the company is the employees salary and if he is a boss the the sum of salarys of the employee and his subordinates
Expected deliverables were:
1.The class structure and
2.Method Float CostToTheCompany(String name)
which returns the cost to the company for the employee whos name is passed
suppose abhishek thakur is passed then the cost to the company will be Abhishek thakur's salary and sum of subordinates salaries working under Abhishek thakur.

and officers. one officer is responsible for each
room. and room has unique room id. a meeting will be
aranged only when the officer and client are free and
room is also free. the officer and clients must be
registered to the system which will give them unique
email ids. arrange the meetings. dont write ode.
2. write a program to find the occurance of charachers
'!', 'replace all odd occurance of '?' to '.'.
3. there was a given program to insert a value at the
proper postion in a doubly linked list. there was some
logical error in that due to which it was not working
properly. find out that error. it was easy.
Sapient test 2nd round
This is also technical round .Duration 1hr
.
You have to write two programs .in any language .preferably c++ and java.
Program 1.
Name : Post - mails
Some conditions are given like if you cover some distance you have to pay this amount , if postal weight is this then u have to pay this amount .
Thus five to six conditions are given , you have to write the program to get the distance of post – mail / sort / print / the result .
Very simple program just use if and else loop .
Given : getdistance() is function which gives you the distance between two cities.
Program 2
Name : compress and decompress the string .
One string is given like : aaabbbbbcddddeeee
You hav to compress the string like a3b5c1d4e4
And it may happen while transferring the compress string some non alphanumeric characters can add in compressed string so compressed string can become a@3b%5c*1d$4e4 like this you have to remove this extra characters.
Those who cleared this test hav technical interview round

joining letter
Sapient
Written
--------
1) Write a program for the problem: the array of
inetegers indicating the marks of the students is
given, U have to calculate the percentile of the
students aaccording to this rule: the percentile of a
student is the %of no of student having marks less
then him. For eg:
suppose
Student Marks
A 12
B 60
C 80
D 71
E 30
F 45
percentile of C = 5/5 *100 = 100 (out of 5 students 5
are having marks less then him)
percentile of B = 3/5*100 = 60% (out of 5, 3 have
markses less then him)
percentile of A = 0/5*100 = 0%.
2) The code was given for a problem and u have to
identitfy the logical error in it. That was simple.
The code was to merge the Danagrams of 2 words. The
danagram of a word is the letters of word arranfed in
sequential order. eg danagram of abhinav is aabhinv.
merging of danamagram is to merge the danagrams of 2
or more words such that the highest no of occurance
are coming for each alphabet.eg
merging of aabhinv and abbhhixz is aabbhhinvxz.
Technical interview:
--------------------
discussion on the written paper. how did u solved the
problem? expain him about that. small discussion on yr
project for a while. simple techinal questions related
to project. simple langugae question : Collections in
java.. types of joins in SQL. if u want to ask
something about sapient etc?
HINT: ask something good. eg kind of projecst they are
doing.. processes they follow .. how do they capture
the requirements .. etc..
Business Inteview:
------------------
Hr inteview.. behaviorial questions.. how will u react
in some conditions.. how how did u reacted..
1) give an example when yr boss is not aggreed with u.
what did u do?
2) give an example when u had a clash with yr peer.
what did u do?
3) give an example when u faced some ambigious
situation.(when u are not understanding the things
properly ) what did u do?
4) give an example when u faced some stressful
situation.what did u do?
5) did u make some decision of yr own to carray out
something. and suggested this to yr boss and yr boss
aggreed?
etc..
what do u want to ask.
HINT : ask some good ques. like how open the
envrionment is? is a junior person part of design??
what is the responsibility of a member for the proper
working of project?
Busines Interview 2
-------------------
This was more of type 2 only. but they will tell about
sapient. and u may ask as many quest as u want. now u
can again ask the same ques ased in previous 2
interviews. '?' '.' ',' etc. Also write a function to
replace all odd occurance of '?' to '.'.
3. there was a given program to insert a value at the
proper postion in a doubly linked list. there was some
logical error in that due to which it was not working
properly. find out that error. it was easy.

Tue, 22 Jul 2008 08:57:00 +0000 - WIPRO Placements Papers
Tue, 22 Jul 2008 08:53:00 +0000 - WIPRO PLACEMENTS PAPER - I
Pattern was same as previous
Verbal 15
Analytical 15
Technical 20
no negative marking
Previous questions were not repeated. If ur good at grammer in ur school level its enuf to clear Verbal.
Analytical was really analytical as there were only 3 or 4 questions from quant. They were pretty easy. Rest all depends on ur talent.
As I am from Electrical& Electronics I felt Technical very tuf. I knew only 4q's in tech that too from C. God was with me. So I got thru the written test.
Suggestion for non CSE and it students is dat dont worry u can answer atleast 6 q's confidently in tech as there were some q's where u can eliminate 3 options in the first look itself.
coming to the Tech Interview
We were given only 10 minutes after the results of the written test were announced.
I was the 3rd to my pannel and was the first to be selected by him.
he: give me ur resume
me: gave him the resume
he: tell me abt ur self
me: I was prepared for it.i gave the answer promptly. I couldnt maintain eye contact initialy but i could manage it.
he: wat do u kno in C
me: basics
he: C++?
me: no. and told him the reason y i didnt learn them outside.
its always better to substantiate such things with a reason.
he: wat is a datatype
me: gave the answer
he: asked something on linked list.
me: I couldnt hear him. so i told him i donno
he: wats the difference bet ms office xp and 2003
me: (i wrote tat in my computer skills) i told him we use only the basic features of ms office. may be there r some internet related features in 2003 which r not there in xp.
the real difference is dat office xp runs in win 98, 2000, and win xp. but 2003 runs only on win xp and win 2000 with servicepack.
he: narrated a big passage. the gist was that whether a file created in office 2003 be opened in office xp.
me: yes sir it can be without a problem
he: r u sure
me: yes sir. i tol him our college has xp and i have 2003 and we often transfer documents.
he: any questions?
me: asked him two questions related to technical only. dat was a plus point for me.
he: then told me to wait outside and told that he will let me kno
me: thank u sir.he forwarded his hand and i did the same and gave a firm shake hand.
within few min I was given a form for hr interview. It was very lengthy and almost took 20 min to fill. Within next 10 min after filling the form I was called for HR interview.
Interviewer was a lady.
she: tell me abt ur ur self
me: tol her same thin letter to letter as i tol in tech.
this time eye contact was not at all a problem
she: (i told her something on my introspection in my intro) she asked gimme an incident as an example.
me:i didnt expect her to ask it.but suddenly an incident flashed into my mind. it really happened in my first year.i told her dat.
she: tell me abt ur family
me : told her
she: y didnt u get placed in CTS and TCS?
me: (cts and tcs came to our college on 3rd of aug) I told her i didnt clear their written.
she: wat did u learn from dat
me: I was not expecting dat but my mind was alert as I was not at all tensed. I told her tat donot fall for temptation from CTS and do not prepare more than ur caliber from TCS.
she: why wipro?
me: I was perpared for this question. i tol her three points abt wipro in which i gave her a hint tat i prefer working in south india.
she: wat if i place u in gurgoan (wipro is there in gurgoan)
me: no problem i will work there for a couple of years and take a transfer and come back to south.
she: wat do u think abt ur college:
me: told her all the good things which i knew abt our college (our college is really popular for its placements, thanks to ur placement officer). first i told her tat our college has good placements and good companies r coming and i also told tat Wipro is one such company
its always good to boost abt ur college though u dont like somethings in ur college describe those points in which ur college is different from other colleges.
then she told me "ok u can leave"
i told thank u and left.
interviews for me were over by 4:15 pm
I waited upto 8 :15 then results were announced and my name was there.
Infact the hr was so easy tat all my friends who cleared tech got thru hr. Some of them were asked only one question: why wipro or why shu i hir u? and they were all selected. EEE students gave their best on tat day.
My suggestion to those preparing for campus placements is dat, do not expect much before u get selected. Write the test as if ur writing ur internals. Be practical, be cool.
Never never never loose in hr interview. So donot expect any questions tat u prepared for. Only two things will be looked for: they r confidence and eye contact and truth in ur answers. So donot bluff.
Before u go for interview learn new things abt ur self which u dont kno and try to boost those in the interview and ur resumes. U kno ur self better than others. If u kno ur self better then u will kno wat to answer for wat.
all the best.
Tue, 22 Jul 2008 08:53:00 +0000 - WIPRO PLACEMENTS PAPER - II
The day started with a pre-placement talk..it was about 45 minutes…he said a lot bout WIPRO…I was satisfied with the presentation..because…there were many opportunities after joining WIPRO….like they have tie up with BITS, IIM’s etc..so they give us an opportunity to do M.Tech..like this many….
After this, immediately there was the written exam…which consisted of 3 sections:
1. verbal
2. analytical
3. technical
there was sectional cut-off but no negative marking…
Verbal was bit easy…it consisted of 15 questions
2 questions on meanings
2 questions on analogy
2 questions on correction of sentence
2 questions on opposites
4 questions on comprehensive passage
2 questions on fill up the blanks with multiple choices
1 odd man out
Over all…to say clearly..this verbal section will be easy for GRE writers…coz…my other frnds said that..all question were from Barron’s
The pattern was entirely changed…only one question was repeated from the old papers n is
CANONIZE:SAINT::
a)train:athiete b)guard:dignitary c)deify:sinner d)lionize:celebrity answer is D
Comprehensive passage was little bit easy…remaining Barron’s will help u…
Next was analytical..see frnds..this time..both previous papers and R.S.Agarwal dint helped me…questions were totally talent based..3 questions were too long..even I dint read them..juz guessed…there were 15 questions…
2 questions were on divisibility…say…
A number when divides with 9, 8, 5, 3 leaves remainder 5,3,6,0..wat is da number…u can do this simply by verifying the options…another was also the same type…
One was on Permutation and combinations…my view is that..to be good in all mathematics basics n general thinking…so dat it would become easy…
Next was the most tuff one of the exam..analytical…god…Iam from biomedical engineering stream..n all question are from java..oracle..unix..only one question was from C n other one from C++ ..
20 questions were asked..gud news is that…wipro management said that…there will be lower cut-of for non-it branches…but this was accepted by them prior to the exam..we informed about this to wipro..on aug 1st…
Over all all 3 sections will be given in one paper…n one omr sheet…time 1 hour for 15+15+20 questions…sectional cut of…no negative marking…so guess a lot…I guessed 17 questions of technical…refer barrons..have gud mathematics basics…have a great knowledge in C n C++..it helps u again in interview…
I was 50-50 about my result..coz my verbal..was a big doubt for me..
Exam was completed by 12:15…results were announced at 1:00…out of 352 members 150 were selected…mine was 3rd batch…interview at 3:30…
I then had a mock interview with my friends….at college..i think it helped me a lot..coz..this was the first interview …
Then..i came to assembly hall by 3:00 with a formal plain shirt n trouser (frnds don’t wear checks type of shirts)…wid shoes…
Our 3:30 batch was called at 4:00…I was the first from our batch…to have interview…
I went in with a big smile…greeted him…he had given a shake hand…and told me to sit…I said thanx…he asked..”tell me bout urself”…this went for 5 minutes…then he said that “iam new to biomedical..tell me about it”…I said bout biomedical engineering for 10 minutes…den he said to list the subjects which we had form 1st year…I listed all of them.. he then asked me bout my paper presentation…he was totally impressed…n den..he asked to tell bout each subject for 1 minute…I said it…n den…asked to write a program on swapping..i said I will use strings..he said no n asked to swap a=3 and b=5….bfore I took pen..he said me 2 explain the procedure….i did it perfectly….den asked bout Inheritance…loops used in C…increment and decrement…bout and & or gates..wid truth table…
He asked why s/w…I said…doing biomedical was passion…but I want 2 work in s/w field desperately….i think he was impressed a lot…wit dis sentence..he den said any questions…I asked one..n had given me an application for HR round…I was on cloud nine…coz…I was confident dat I will be placed in wipro…
Then…Hr was juzz for formal…it was for 3 minutes..he asked—“tell me about urself”…n “tell bout ur paper”…dats all
I was confident that..i will be placed in WIPRO…
90 were selected for HR…
Interviews were upto 10:00 pm….results was announced at 10:40…ohh god….i was one among 66….
Friends..i say clearly…juzz be confident…if u r saying false…be confident…
all the best.
