Java Tutorial : Java Assignment Operators

AssignmentOperatorDemo1.java

class AssignmentOperatorDemo1
{
    public static void main(String[] args)
    {

        int a = 5;
        int b = 2;

        /*
         * Assigns value from right side operands to left side operand.
         */
        a = b;

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

    }
}

Output

a = 2

AssignmentOperatorDemo2.java

class AssignmentOperatorDemo2
{
    public static void main(String[] args)
    {

        int a = 5;
        int b = 2;

        /*
         * Adds right operand to the left operand and assign the result to left.
         * 
         * a+=b is same as a=a+b
         */
        a += b;

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

    }
}

Output

a = 7

AssignmentOperatorDemo3.java

class AssignmentOperatorDemo3
{
    public static void main(String[] args)
    {

        int a = 5;
        int b = 2;

        /*
         * subtracts right operand from the left operand and assign the result
         * to left operand.
         * 
         * a-=b is same as a=a-b
         */
        a -= b;

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

    }
}

Output

a = 3

AssignmentOperatorDemo4.java

class AssignmentOperatorDemo4
{
    public static void main(String[] args)
    {

        int a = 5;
        int b = 2;

        /*
         * mutiply left operand with the right operand and assign the result to
         * left operand.
         * 
         * a*=b is same as a=a*b
         */
        a *= b;

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

    }
}

Output

a = 10

AssignmentOperatorDemo5.java

class AssignmentOperatorDemo5
{
    public static void main(String[] args)
    {

        int a = 5;
        int b = 2;

        /*
         * Adds right operand to the left operand and assign the result to left.
         * 
         * same as a=a/b
         */
        a /= b;

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

    }
}

Output

a = 2

AssignmentOperatorDemo6.java

class AssignmentOperatorDemo6
{
    public static void main(String[] args)
    {

        int a = 5;
        int b = 2;

        /*
         * calculate modulus using two operands and assign the result to left
         * operand.
         * 
         * a%=b is same as a=a%b
         */
        a %= b;

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

    }
}
