Like every year, this year also this site wishes best of luck to all ICSE 2013 students. Students who are following my site are expected to score better marks in ICSE 2013 Computer examination. In this post, I am trying to point out some guess questions in the forthcoming examination and few suggestions.
Theory part in ICSE 2013 Computer Application
Please go through the following topics and I think this would help you in 2013 ICSE Computer Application paper.
What is Object Oriented Programming
What is object in Object Oriented Programming
What is Class in Object Oriented Programming
What is Constructor
What is Encapsulation in BlueJ
Name any two library packages of java .
What is meant by a user defined data type?
Give an example of syntax error
What is the scope of the keyword protected in accessing functions?
What is a parameterized constructor?
What is the use of static in the main function?
Arithmetic Assignment Operator in BlueJ
Increment and Decrement Operators in Java
Pre conditions of binary search
Show the use of logical operator && with an example.
Explain the term – “pass by reference”.
Differentiate between indexOf() and valueOf() functions.
Several functions of String class.
Difference between equals () function and == operator.
Break and Continue in BlueJ
Comparison Among Different Loops
while and do-while
while and for
Syntax of Different Decision Making Statements
Differentiate between isUpperCase() and toUpperCase() function.
Advantages of Exception handling.
What is a “fall through” situation in switch case statement.
Write any two rules for naming varible declaration.
Write down the difference between prefix and postfix operators.
Conditional operator.
What is meant by polymorphism? Give an example.
State difference between call-by-value and call-by-reference.
Write any two differences in Implicit Type Casting and Explicit Type Casting.
What is a function?
Can there be objects without having any functions?
Why are functions so important for the description of objects?
What is an abstraction?
Can there be multiple abstractions of a real world entity
How are classes and abstraction linked?
What is an object factory?
Use of static keyword in bluej programs
Use of static in variable
What is static method or function
Function calling techniques-Call be reference and call by value in BlueJ
Use of break statement in BlueJ Programs
Use of Scanner class in BlueJ programs
What is private and public specifier in Java?
Difference between ‘==’ and equals ()’.
Compare switch with else-if ladder.
Define ‘substring ()’ and ‘charAt()’ function.
Comparision between break and continue
Use of ‘this’ keyword.
What do you mean by data encapsulation and polymorphism in Java?
Name the package you need to import for using Scanner class object.
State the difference between while and do-while loop
State the difference between constructor and function
Explain any two type of access specifiers
What are the preconditions of binary search?
What is the role of void keyword in declaration of a function
What is package, give example.
Explain function overloading with example
What is exit control loop? Give example
What is recursive function, give example
So far as programs are concerned, one program on else if ladder ( either tax calculation, discount calculation or bill calculation) is confirmed. Programs on different numbers like perfect number, prime number etc can be expected. In every year ICSE Computer Application paper, one or two programs are found where the questions are very lengthy but the programs are normally very simple. My advice is to read the question carefully and the solution will be very easy.
Thank You so much! :)
