JAVA TUTORIAL PART 2 – ASSIGNMENT OPERATORS

There are following Assignment Operators Supported by Java Language:

 OPERATOR : =      

DESCRIPTION :

Simple Assignment Operator, Assigns values from Right Side Operands to Left Side Operand   

EXAMPLE :

C = A + B will Assign Value of A + B into C

OPERATOR :  +=      

DESCRIPTION :

Add AND Assignment Operator, It ADDS Right Operand to the Left Operand and Assign the Result to Left Operand          

EXAMPLE :

C += A is Equivalent to C = C + A

OPERATOR :  -=       

DESCRIPTION :

Subtract AND Assignment Operator, It SUBTRACTS Right Operand from the Left Operand and assign the Result to Left Operand   

EXAMPLE :

C -= A is Equivalent to C = C – A

OPERATOR : *=       

DESCRIPTION :

Multiply AND Assignment Operator, It MULTIPLIES Right Operand with the Left Operand and Assign the Result to Left Operand   

EXAMPLE :

C *= A is Equivalent to C = C * A

OPERATOR : /=       

DESCRIPTION :

Divide AND Assignment Operator, It DIVIDES Left Operand with the Right Operand and Assign the Result to Left Operand          

EXAMPLE :

C /= A is Equivalent to C = C / A

OPERATOR : %=      

DESCRIPTION :

Modulus AND Assignment Operator, It takes MODULUS using Two Operands and Assign the Result to Left Operand          

EXAMPLE :

C %= A is Equivalent to C = C % A

OPERATOR : <<=     

DESCRIPTION :

Left Shift AND Assignment Operator

EXAMPLE :

C <<= 2 is SAME as C = C << 2

OPERATOR  : >>=    

DESCRIPTION :

Right Shift AND Assignment Operator

EXAMPLE :

C >>= 2 is SAME as C = C >> 2

OPERATOR : &=      

DESCRIPTION :

Bitwise AND Assignment Operator

EXAMPLE :

C &= 2 is SAME as C = C & 2

OPERATOR : ^=       

DESCRIPTION :

Bitwise Exclusive OR and Assignment Operator

EXAMPLE :

C ^= 2 is SAME as C = C ^ 2

OPERATOR : |=        

DESCRIPTION :

Bitwise Inclusive OR and Assignment Operator

EXAMPLE :

C |= 2 is SAME as C = C | 2

Example Program :

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;

 %= 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 >>= a = ” + c );

 c &= a ;

System.out.println(“c &= 2  = ” + c );

c ^= a ;

System.out.println(“c ^= a   = ” + c );

c |= a ;

System.out.println(“c |= a   = ” + c );

}

}

Result:

 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
