/*
 * ============================================================================
 * Program Name : Assignment Operators
 * File Name    : 009-Assignment-Operators.java
 * Class Name   : AssignmentOperators
 *
 * Description:
 * This program demonstrates the use of assignment operators in Java.
 * Assignment operators are used to assign values to variables and
 * perform arithmetic operations along with assignment.
 *
 * Assignment Operators:
 * =   Assign
 * +=  Add and Assign
 * -=  Subtract and Assign
 * *=  Multiply and Assign
 * /=  Divide and Assign
 * %=  Modulus and Assign
 *
 * Objective:
 * - Understand assignment operators in Java.
 * - Learn how compound assignment operators work.
 * - Display the updated value after each operation.
