Java Compound Assignment Operators

In this chapter you will learn:

1. What are Arithmetic Compound Assignment Operators
2. Syntax for Arithmetic Compound Assignment Operators
3. Example - Arithmetic Compound Assignment Operators

Description

Statements like the following

a = a + 4;

can be rewritten as

a += 4;

Both statements perform the same action: they increase the value of a by 4.

Syntax

Any statement of the form

var = var op expression;

can be rewritten as

var op= expression;

Example

Here is a sample program that shows several op= operator assignments:

 
public class Main {
/*from   w  ww.ja v a2 s. c o  m*/
  public static void main(String args[]) {
    int a = 1;
    int b = 2;
    int c = 3;

    a += 1;
    b *= 2;
    c += a * b;
    c %= 3;
    System.out.println("a = " + a);
    System.out.println("b = " + b);
    System.out.println("c = " + c);

  }
}

The output of this program is shown here:
