Reading Terminal Or DOS Input Using SavitchIn Java Class

Class for simple console input. A class designed primarily for simple keyboard input of the form one input value per line. If the user enters an improper input, i.e., an input of the wrong type or a blank line, then the user is prompted to reenter the input and given a brief explanation of what is required. Also includes some additional methods to input single numbers, words, and characters, without going to the next line.

01	public class Usage {

02	public static void main(String [] args) {

03	// for string input
