Stack : http://www.guideforschool.com/2266492-operation-on-stack-using-java/
Queue : http://www.guideforschool.com/2291515-operation-on-queue-using-java/
Sir, Please provide the solution of ISC 2016 Computer Science Theory Specimen Paper Question no.1.
I have tried it many times but still I am unable to solve it
While doing program for queue, sometimes it is asked to initialize front and rear with 0. In such case how to proceed for pushing and popping elements in the queue??
See: http://www.guideforschool.com/2291515-operation-on-queue-using-java/
very helpful site …… exam was so easy thank u soo much
It was really helpful….:) I visited this site fo the first time and i find it a great guide for students….Thank you so much…!!!
But I have a query in programming…I want to know how can we print a number(double or triple digit) in words…for eg-
119 as one hundred and nineteen and 29 as twenty nine..it would be really nice if i am answered….:)
Hello Saumya, thanks for your appreciation.
Here is the program you are looking for: http://www.guideforschool.com/1218147-isc-2011-question-1-practical-paper-solved-number-in-word/
Hope you visit us often.
sir can you please tell me how to initialize a character input using Scanner Class in bluej??
System.out.print("Enter any Character: "); char c = sc.next().charAt(0);sir, what is a copy constructor and how, where and when should i use it?
Copy constructor is a constructor which copies values of the instance variables of an object into another object. It is hence used to create duplicate objects.
this website is very helpful…
what is type casting???today i was unable to answer this question in my exam
Type Casting refers to Explicit type conversion i.e. When the conversion takes place with the programmer’s intervention
See: http://www.guideforschool.com/1465944-isc-computer-practical-viva-questions/
Sir i would like to about the programs on anagrams.
like if the input is TOP
the output should be TOP, TPO, OPT, OTP, POT, PTO.
kindly help.

Sure Prithviraj, go through the programs in this link: http://www.guideforschool.com/category/inheritance-related-programs/
Sir, i am in class 11,studying in Julien Day school and have my practicals tomorrow.
Sir,is step marking given if the program doesn’t run(like in half yearly practicals,i got 70 out of 100 even the program dint run,typed program fast and answered all the viva questions).
It is upto the school teacher how they evaluate in your schools. But in the final ISC practical examination, the paper is of 80 marks divided into 6 parts. Read them here: http://www.guideforschool.com/wp-content/uploads/2014/02/ISC-2014-Computer-Science-Paper-2-Practical.pdf
Aswumness at its peak!!
Thanks a lot JFS… 😀
You are a real genius! I m quite confident about my today’s practical exam and u have a big hand in my achievement. I will continue to be the follower of ur website n I m sure that it would help in my theory exam as well. Thanx once again!
sir where encapsulation concpt is used
When you create a class, you are actually implementing the encapsulation concept.
Encapsulation states that the data and its associated functions are wrapped inside a class.
What kinds of questions are asked in Viva? please tell as we have our parcticals tomorrow….
See: http://www.guideforschool.com/1465944-isc-computer-practical-viva-questions/
Sir Please give me one complete written algorithm for any string operation Bcoz I m confused for tomorrow’s practical………pls reply fast sir
See the example 2 in this post: http://www.guideforschool.com/1611744-advice-on-how-to-write-algorithm-in-isc-computer-practical/
thank you sir
this site rocks
will the viva questions also include memory address calculations and conversion of infix to prefix and postfix? please reply asap.
No.
do we need to prepare recursion for tomorrow’s practical exam. please reply asap.
No.
Sir , please solve following program ,which I am unable to solve.The program is :
Write a program in java to accept two date in dd/mm/yyyy format and display the number of days in between them.
Example :–
INPUT : DATE 1 — 02/05/2012
DATE 2 — 06/06/2012
OUTPUT : DAY DIFFERENCE = 35
INPUT : DATE 1 — 02/05/2012
DATE 2 — 06/05/2012
OUTPUT : DAY DIFFERENCE = 4
INPUT : DATE 1 — 02/12/2010
DATE 2 — 06/01/2011
OUTPUT : DAY DIFFERENCE = 35
The program has already been solved. See: http://www.guideforschool.com/350-java-program-for-finding-difference-between-2-dates/
Sir,what does trim() function do?
It removes any white space present before or after a string.
Example: The string ” Java For School ” will become “Java For School” if you apply trim() function to it.
Sir kindly let me know whether we can use Scanner class in place of String tokenizer in our ISC Computer Practical Exam
Yes you can use Scanner class.
Sir need your help in two programs.
1.Wap to input a date and print in dd/mm/yyyy format(Input:01011943 Output: 01/10/1943)

Sir can I use util package in linked list programs?By using util package I think program’s length will be shortened.Please reply sir. Marks will be given or not if we use util package and do programs.
No, you cannot use the functions of LinkedList class from the java.util package.
I know it makes linked lists program easier as you have pre-defined functions for various operations, but, that is not in your syllabus.
Sir can u please tell how to search for an name in linked list?
Can we use util package in linked list program?
