Compound assignment operators in Java
The Assignment Operators
Following are the assignment operators supported by Java language −
| Operator | Description | Example |
|---|---|---|
| = | Simple assignment operator. Assigns values from right side operands to left side operand. | C = A + B will assign value of A + B into C |
| += | Add AND assignment operator. It adds right operand to the left operand and assigns the result to left operand. | C += A is equivalent to C = C + A |
| -= | Subtract AND assignment operator. It subtracts the right operand from the left operand and assigns the result to left operand. | C -= A is equivalent to C = C � A |
| *= | Multiply AND assignment operator. It multiplies right operand with the left operand and assigns the result to the left operand. | C *= A is equivalent to C = C * A |
| /= | Divide AND assignment operator. It divides the left operand with the right operand and assigns the result to left operand. | C /= A is equivalent to C = C / A |
| %= | Modulus AND assignment operator. It takes modulus using two operands and assigns the result to left operand. | C %= A is equivalent to C = C % A |
| <<= | Left shift AND assignment operator. | C <<= 2 is same as C = C << 2 |
| >>= | Right shift AND assignment operator. | C >>= 2 is same as C = C >> 2 |
| &= | Bitwise AND assignment operator. | C &= 2 is same as C = C & 2 |
| ^= | bitwise exclusive OR and assignment operator. | C ^= 2 is same as C = C ^ 2 |
| |= | bitwise inclusive OR and assignment operator. | C |= 2 is same as C = C | 2 |
Example
public class Test {
public static void main(String args[]) {
int a = 10;
int b = 20;
int c = 0;
c = a + b;
System.out.println("c = a + b = " + c );
c += a ;
System.out.println("c += a = " + c );
c -= a ;
System.out.println("c -= a = " + c );
c *= a ;
System.out.println("c *= a = " + c );
a = 10;
c = 15;
c /= a ;
System.out.println("c /= a = " + c );
a = 10;
c = 15;
c %= a ;
System.out.println("c %= a = " + c );
c <<= 2 ;
System.out.println("c <<= 2 = " + c );
c >>= 2 ;
System.out.println("c >>= 2 = " + c );
c >>= 2 ;
System.out.println("c >>= 2 = " + c );
c &= a ;
System.out.println("c &= a = " + c );
c ^= a ;
System.out.println("c ^= a = " + c );
c |= a ;
System.out.println("c |= a = " + c );
}
}This will produce the following result −
Output
c = a + b = 30 c += a = 40 c -= a = 30 c *= a = 300 c /= a = 1 c %= a = 5 c <<= 2 = 20 c >>= 2 = 5 c >>= 2 = 1 c &= a = 0 c ^= a = 10 c |= a = 10
