hi mate,

Answer :

Increment and Decrement Operators in Java

• Increment and decrement operators in Java are also known as unary operators because they operate on a single operand. The increment operator (++) adds 1 to its operand and decrement operator (–) subtracts one.

• Operator Meaning
• ++ Increment Operator
• — Decrement Operator

• Syntax:-

• ++variable; // pre increment operator
• variable++; // post increment operator
• --variable; // pre decrement operator
• variable--; // post decrement operator

• Expression The initial

• The final
• value of a Value x
• x = ++a 4 5 5
• x = a++ 4 5 4
• x = –a 4 3 3
• x = a– 4 3 4

• Increment operators (++)

• First, the value of the variable a incremented by 1 and store in the memory location of variable a.
• Second, the value of variable a assign to the variable x.

• class PreIncrementOperator{

public static void main

(String[] args) {

int a, x;

a = 10;

x= ++a;

System.out.println("a: "+a);

System.out.println("x: "+x);

}

}

• Output:-
• a: 11
• x: 11

• Decrement Operators ( -- )
• Pre-decrement operator in Java ( --a )

• First, the value of a decremented by 1 and store in the memory location of variable a.
• Second, the value of the variable a assigned to the variable x.

• class PreDecrementOperator

{

public static void main(String[] args) {

int a, x;

a = 10;

x = --a;

System.out.println("a: "+a);

System.out.println("x: "+x);

}

}

• Output:-
• x: 9
• y: 9

i hope it helps you.

Answer 2

Answer:

1.Java Interview program on pre increment operator.

1. package com.instanceofjava;
3. class IncrementDemo{
5. public static void main(String [] args){
7. int a, b;
8. a=10;
9. b=++a;
10. System.out.println(b);
12. }
13. }

Output:

1. 11

2.Java Interview program on post increment operator.

1. package com.instanceofjava;
3. class IncrementDemo{
5. public static void main(String [] args){
7. int a, b;
8. a=10;
9. b=a++;
10. System.out.println(a);
12. }
13. }

Output:

1. 11
