 * Program Name : Read Multiple Inputs
 * File Name    : 015-Read-Multiple-Inputs.java
 * Class Name   : ReadMultipleInputs
 *
 * Description:
 * This program demonstrates how to read multiple types of input from
 * the user using the Scanner class in Java. It accepts an integer,
 * a double, a character, a boolean, and a String from the keyboard.
 *
 * Objective:
 * - Understand how to read multiple inputs using Scanner.
 * - Learn different Scanner methods for different data types.
 * - Display all the values entered by the user.
