/*
 * ============================================================================
 * Program Name : Logical Operators
 * File Name    : 008-Logical-Operators.java
 * Class Name   : LogicalOperators
 *
 * Description:
 * This program demonstrates the use of logical operators in Java.
 * Logical operators are used to combine two or more boolean expressions
 * and return a boolean result (true or false).
 *
 * Logical Operators:
 * &&  Logical AND
 * ||  Logical OR
 * !   Logical NOT
 *
 * Objective:
 * - Understand logical operators in Java.
 * - Learn how to combine boolean expressions.
 * - Display the result of logical operations.
