Java Addition Assignment (+=) Operator

Java Addition Assignment

In Java, Addition Assignment Operator is used to add a value (right operand) to this variable (left operand) and assign the result back to this variable (left operand). In this tutorial, we will learn how to use Addition Assignment operator in Java, with examples.

The syntax to add a value of 2 to variable x and assign the result to x using Addition Assignment Operator is

x += 2

Example

In the following example, we take a variable x with an initial value of 5, add a value of 2 to x and assign the result to x, using Addition Assignment Operator.

Main.java

public class Main {
    public static void main(String[] args) {
        int x = 5;
        //addition assignment
        x += 2;
        System.out.println("x : " + x);
    }
}

Output

x : 7
