Assignment Operator in Java with Example

What is an Operator in Java?

Operators are special symbols that perform the specified operations. Each operator is responsible to perform some specific operation on variables or values and return a result. The operators are classified and listed according to precedence order.

Java supports the following types of operators:

What is Assignment Operator in Java?

An Assignment Operator is an operator used to assign a new value to a variable. The assignment operator assigns a value from the right side operand or value to the left side operand.

For example, int year = 2022; here, = is an assignment operator. It assigns the '2022' value to its left side operand 'year'.

Java has provided the following types of assignment operators, see the given table below.

Operator	Description	Example	Equivalent to
=	Assigns value from right side operand to left side operand	z = y	z = y
+=	It adds right operand to the left operand and assigns the result to left operand	x += y	x = x + y
-=	It subtracts right operand from the left operand and assigns the result to left operand	x -= y	x = x - y
*=	It multiplies right operand with the left operand and assigns the result to left operand	x *= y	x = x * y
/=	It divides left operand with the right operand and assigns the result to left operand	x /= y	x = x / y
%=	It takes modulus using two operands and assigns the result to left operand	x %= y	x = x % y
^=	Performs exponential (power) calculation on operators and assign value to the left operand	x ^= y	x = x ^ y

Operator

Description

Example

Equivalent to

Assigns value from right side operand to left side operand

z = y

It adds right operand to the left operand and assigns the result to left operand

x += y

x = x + y

It subtracts right operand from the left operand and assigns the result to left operand

x -= y

x = x - y

It multiplies right operand with the left operand and assigns the result to left operand

x *= y

x = x * y

It divides left operand with the right operand and assigns the result to left operand

x /= y

x = x / y

It takes modulus using two operands and assigns the result to left operand

x %= y

x = x % y

Performs exponential (power) calculation on operators and assign value to the left operand

x ^= y

x = x ^ y

  public class AssignmentOperatorsDemo {
    public static void main(String[] args) {
      int x = 10;
      int y = 20;
      int z;
      
      System.out.println(z = x);          // Output = 10
      System.out.println(y += x);         // Output = 30
      System.out.println(y -= x);         // Output = 20
      System.out.println(y *= x);         // Output = 200
      System.out.println(y /= x);         // Output = 20
      System.out.println(y %= x);         // Output = 0
      System.out.println(y ^= x);         // Output = 10
    }
  }
