Last Year Paper for ICSE Computer Application

Will you please give me question paper for class 10th computer application examination of ICSE??

Here I am giving you question paper for class 10th computer application examination of ICSE in word file with it …

Some questions are given below :
Question 1
a) What is meant by precedence of operators? [2]
Ans. Precedence of operators refers to the order in which the operators are applied to the operands in an expression. For example, * has higher precedence than +. So, the expression 8 + 2 * 5 will evaluate to 8 + 10 = 18

b) What is a literal? [2]
Ans. A literal is a constant data item. There are different literals like integer literals, floating point literals and character literals.

c) State the Java concept that is implemented through:
i) a super class and a subclass.
ii) the act of representing essential features without including background details. [2]
Ans. i) Inheritance
ii) Abstraction

d) Give a difference between constructor and method. [2]
Ans. i)A constructor has no return type which a method has a return type.
ii) The name of the constructor should be the same as that of the class while the name of a method can be any valid identifier.
iii) A constructor is automatically called upon object creation while methods are invoked explicitly.

e) What are the types of casting shown by the following examples? [2]
i) double x =15.2;
int y =(int) x;
ii) int x =12;
long y = x;
Ans. i) Explicit casting
ii) Implicit casting

Question 2:
a) Name any two wrapper classes. [2]
Ans. Byte, Short, Integer, Long, Float, Double, Boolean, Character

b) What is the difference between break and continue statements when they occur in a loop. [2]
Ans. The break statement terminates the loop while the continue statements current iteration of the loop to be skipped and continues with the next iteration.

c) Write statements to show how finding the length of a character array and char[] differs from finding the length of a String object str. [2]
Ans. The length of a character array is found by accessing the length attribute of the array as shown below:
char[] array = new char[7];
int lengthOfCharArray = array.length;
The length of a String object is found by invoking the length() method which returns the length as an int.
String str = “java”;
int lengthOfString = str.length();
