Java Subtraction Assignment

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

The syntax to subtract a value of 2 from variable x and assign the result to x using Subtraction Assignment Operator is

</>
Copy
x -= 2

Example

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

Main.java

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

Output

x : 3
