Java Assignment Operators

The Java Assignment operators are used to assign the values to the declared variables. Equals ( = ) operator is the most commonly used assignment operator in Java. For example:

int i = 25;

Below table displays all the assignment operators present in Java programming language.

Assignment Operators in Java	Example	Explanation
=	x = 9	Value 25 is assigned to x
+=	x += 9	This is same as x = x + 9
-=	x -= 9	This is same as x = x – 9
*=	x *= 9	This is same as x = x * 9
/=	x /= 9	This is same as x = x / 9
%=	x %= 9	This is same as x = x % 9

Java Assignment Operators example

In this Java Program, We are using two integer variables a and Sum.. We are going to use these two variables to show you the working functionality of all the Assignment Operators in Java Programming Language

JAVA CODE

// Program for Java Assignment Operators 
package JavaOperators;

import java.util.Scanner;

public class AssignmentOperators {
	private static Scanner sc;
	public static void main(String[] args) {
		int a, Sum;
		sc = new Scanner(System.in);
		System.out.println(" Please Enter any integer Value: ");
		a = sc.nextInt();
		System.out.println(" Please Enter any integer Value for Total: ");
		Sum = sc.nextInt();
		
		System.out.format(" Value of Sum = %d \n", Sum += a );
		System.out.format(" Value of Sum = %d \n", Sum -= a );
		System.out.format(" Value of Sum = %d \n", Sum *= a );
		System.out.format(" Value of Sum = %d \n", Sum /= a );
		System.out.format(" Value of Sum = %d \n", Sum %= a );
	}
}

OUTPUT

ANALYSIS

Following statement will ask the user to enter integer value a and we are going to assign the user input value to integer variable a.

System.out.println(" Please Enter any integer Value: ");
a = sc.nextInt();

Following statement will ask the user to enter integer value Sum and we are going to assign the user input value to integer variable Sum.

System.out.println(" Please Enter any integer Value for Total: ");
Sum = sc.nextInt();

Next line, we performed all the assignemnet operations on a and Sum variables using available in java assignment operators.

Let us see the functionality

System.out.format(" Value of Sum = %d \n", Sum += a );

Sum += a means

Sum = Sum + a ==> 25 + 4 = 29

System.out.format(" Value of Sum = %d \n", Sum -= a );

Sum -= a means

Sum = Sum – a ==> 29 – 4 = 25

System.out.format(" Value of Sum = %d \n", Sum *= a );

Sum *= a means

Sum = Sum * a ==> 25 * 4 = 100

System.out.format(" Value of Sum = %d \n", Sum /= a );

Sum /= a means

Sum = Sum / a ==> 100 / 4 = 25

System.out.format(" Value of Sum = %d \n", Sum %= a );

Sum %= a means

Sum = Sum % a ==> 25 % 4 = 1 (Remainder of 25 / 4 is = 1)
