Introduction to Assignment Operators

Assignment operator is one of Java operators. Simple assignment operator “=” contains two operands.  It assigns the value on its right operand to the operand on its left.  For example, the assignment operator is used to assign a value to a variable.

Syntax

operand = operand;

Example

1.  /**
2.  * @(#)SimpleAssignmentOperatorDemo.java
3.  *
4.  *
5.  * @author
6.  * @version 1.00 2009/11/2
7.  */
8.
9.  public class SimpleAssignmentOperatorDemo {
10.        
11. /**
12.    * Creates a new instance of SimpleAssignmentOperatorDemo.
13. */
14.   
15.    public SimpleAssignmentOperatorDemo() {
16.  }
17.    
18. /**
19.     * @param args the command line arguments
20. */
21. public static void main(String[] args) {
22.     // TODO code application logic here
23.        
24.     int b = 100; // Assign 100 to variable b by assignment operator "="
25.      
26.     int c = b; // Assign value of b to variable c
27.        
28.     System.out.println("Value of b is: " + b);
29.     System.out.println("Value of c is: " + c);
30.
31.   }
32. }

Output

Value of b is: 100
Value of c is: 100
