ISC 2018 Theoretical and Practical Exam Suggestion

In this page you will get suggestions for ISC Computer application theory examination 2018. The entire syllabus is to be covered by all students but I'll point out few chapters or topics which needs more attention for the exam purpose.

1. Recursive function: Students are advised to understand recursive function properly. I can assure that at least one program would be there in your Computer application theory examination paper 2018 with a recursive function. Prepare your self with programs like displaying the sum of a series where the numerator and denominator are generated using recursive function.

2. Inheritance, function overriding and use of super keyword: A simple program on inheritance is expected in Computer application theory examination 2018. The program would be as follows - Initialise the super class and sub class date members through constructors and thus use of super keyword inside sub class constructor body. A specific function would display the super class data member values and the overridden function in the sub class displaying the data members declared in the sub class. This type of display will also need to use super keyword  inside the overridden function body.

3. Program on Linked List, Stack and Queue: A class definition for creating a linked list will be given and the students have to write either algorithm or procedure of performing different jobs like inserting a node at the beginning, searching value etc. Stack and Queue programs using array is very important.

So far as Linked List is concerned, there won't be any program but students will have to write a model function or algorithm for insertion, deletion or searching operation on Linked List.


4. Tree Traversal: A given tree is to be traversed in pre-order, post-order and in-order.

Last Minute Suggestion for ISC 2015 Computer Practical Exam

Like every year this year also I hope that this article will help the students appearing in ISC 2015 Computer practical exam.  Students will get three questions and they have to answer one.

Which program may come in ISC 2015 Computer practical exam?

Program on String class is very common so far as last few years questions are considered. String class, StringTokenizer and different methods (function) of both the classes like indexOf(), substring(), hasMoreTokens(), nextToken() and so on should be well prepared as they will be needed to do your program as well as examiner can ask about the functions in viva voce.

Another program can be expected from numeric value involving else if ladder. Programs on numeric array is very common in ISC practical of Computer Application.

Viva Voce of ISC 2015 Computer Practical

Examiner may ask questions on:

String class functions like indexOf() and substring () - all the overloaded versions of the functions.

Different overloaded constructors of StringTokenizer class.

Basic idea about Exception handling is also very important.

Difference between constructor and function.

Difference between switch and else if ladder.

About ISC Computer Practical – writing the program and Viva Voce Questions

ISC students get three programs in their computer practical and they have to answer only one. Fiirstly they have to write the program on their copy along with algorithm and variable descriptions. Once they have completed their writing job, they cannot modify their copy anymore.

The next step of the practical examination is that they will edit the program on BlueJ editor following their copy. It may happen that the program may show many errors – compile time or run time. There may be logical error also. Don’t worry, rectify the program on computer but don’t try to rectify in your copy. Certain percentage of deviation between the program on your copy and computer is permitted.

Atleast one program of ISC computer practical is based on String class. In viva, details about different String class methods (which are used in your program) are asked by the external examiner. Return type of the methods, other overloaded versions of the methods may be asked. In your program there may be ‘throws’ clause. The examiner may ask the meaning of throws – what actually it throws and to whom. The examiner may ask in viva about Exception handling.

Difference between bubble sort and selection sort is a common question in ISC computer practical examination viva. My observation is that most of the students do not use ‘break’ in bubble sort (I am also an external examiner of a school for last 4-5 years). Students should know the utility of ‘break’ statement in bubble sort.

If there is any program where StringTokenizer class is used, in viva the examiner may ask about the other overloaded version of constructors of the class.

BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); - questions may come from the above statement. What is System.in? What is the need of creating object of InputStreamReader by using the statement new InputStreamReader? Who carries the terminal input towards program in the above statement?

Regarding Exception handling - what is the difference between throws and try...catch.

Use of valueOf () function of String class and toString () function of Object class.

valueOf () is a static function of String class which converts any type of non string value into String object.
toString () is a function of Object which is automatically called by java compiler when any non string value is passed as argument in print () and println() function. This function also converts the non string value into string value. Example:
System.out.println("Value="+a)
Suppose value of 'a' is 5. The function toString () will be called automatically and numeric 5 will be converted into "5". Here '+' operator concatenates the strings "Value=" and "5" into "Value=5".

Describe each terms of System.out.println()

System.is a class of java.lang package. 'out' is the object of PrintWriter class of Java.io package which is a static data member of System class and println () is the function of PrintWriter class.

Example of operator overloading in java

print () and println () functions displays only string values. In the statement System.out.println("Value="+a), addition between a string value and an numeric value is not possible. toString () function of Object class converts the numeric value into string value and then '+' operator concatenates the string values into one string value. This is an example of operator overloading.

I wish Best of luck to all students appearing in computer practical examination on 20th February 2014.

Last Minute Suggession

Suggestion for theoretical paper in ISC 2014 computer application examination

Like every year, this year also I would like to give suggestion for ISC students on computer application examination in 2014. Firstly I would like to say that go throughly through the text book. If possible go through Complete Reference Java by Schield. The book is for software professionals and Engineering college students still school students can go through selected chapters the book. Students should pay more attention on the following topics:

Inheritance in Java
Difference between static and instance member.
Difference between member function and constructor
Binary search and linear search technique.
String class and Math class functions - short notes on the functions.
Binary search tree, stack and queue.
Different decision making techniques with their similarities and differences.
Different loops with their similarities and differences.

So far as String class and Math class functions are concerned, only short notes to be prapared. Do not forget to write the prototypes of the functions with short description.

Programs on String using String functions, programs on else if ladder are very common. For Binary search tree, traversal of tree and making a tree from any two order of traversal is important. Converting infix expression to postfix expression using stack is also important.

Last minute suggestions on guess computer application – theory and practical questions for ISC 2013 students

ISC computer practical examination carries 100 marks and in this site students can get the programs and solutions of previous year papers. From those practical papers, one can guess what type of question may come in ISC 2013 computer application examination.

Practical computer application for ISC 2013

If we look back to previous years papers, the findings can be summed up as follows:

In 2010 ISC computer application practical examination, the first program was on number. The amount was entered by user and the amount was displayed in words and the denomination available in descending order was also displayed. Second program on the same year was on kaprekar numbers in a specific range and the third program was completely on string.


In ISC 2011 computer application practical paper, the first program was on displaying number in word like if the entered value is 29, the output will be: TWENTY NINE
Second program was again on string, encryption of message and the third was on displaying total number of days of a specific date from the start of year which was an int type array program.

In 2012 ISC computer application practical paper, the first program was on prime-palindrome integers within a range.The second one was on string, manipulation with words
And the third was on 2-d array finding largest and smallest  numbers with position.

From the above it is clear that programs on string and array ( both 1-d and 2-d) are common in all the previous years. This year students of ISC 2013 can expect programs from the following list in their practical examination.


Program on queue, queue implementation of queue for printing job or like that.

BlueJ program on String array - arranging the words in ascending order

Write a program to accept a date in the string format (dd/mm/yyyy) and accept the name of the day on 1st January of the corresponding year. Find the day for the given date.

BlueJ program on decoding encoded string with removing extra blank spaces and modification on alphabet cases

Program on 2-d array may be set in 2013 Computer application practical of ISC 2013. The program may be of finding maximum value row wise and columkn wise, sorting the elements etc .

Reversing words of a string

Finding unique digit numbers

BlueJ Program on displaying date in specific format

BlueJ program on valid Email id checking

Program to reverse a string. Example: Input:I like computer applications Output:I ekil retupmoc snoitacilppa.

BlueJ program on circular decoding

BlueJ program on re-arranging numbers in an array with positive numbers first

BlueJ program to find the total number of days between two dates
