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:
|
1 |
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
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
// 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.
|
1 2 |
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.
|
1 2 |
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
|
1 |
System.out.format(" Value of Sum = %d \n", Sum += a ); |
Sum += a means
Sum = Sum + a ==> 25 + 4 = 29
|
1 |
System.out.format(" Value of Sum = %d \n", Sum -= a ); |
Sum -= a means
Sum = Sum – a ==> 29 – 4 = 25
|
1 |
System.out.format(" Value of Sum = %d \n", Sum *= a ); |
Sum *= a means
Sum = Sum * a ==> 25 * 4 = 100
|
1 |
System.out.format(" Value of Sum = %d \n", Sum /= a ); |
Sum /= a means
Sum = Sum / a ==> 100 / 4 = 25
|
1 |
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)
