Question

Write a Java program that directs the user to enter a single word (of at least four characters in length) as input and then prints the word out in reverse in the pattern shown below (please note that the spaces added between each letter are important and should be part of the program you write):

<Sample Output

Enter a word (at least four characters in length): cat

Word must be at least four characters in length, please try again. Enter a word (at least four characters in length): mountain

ח

ni

nia

niat

niatn

niatnu

naitanui

niat nuom

<End Output

If the user enters more than a single word, your program should perform the pattern with only the first word entered by the user:

Enter a word (at least four characters in length): Eggs Benedict

s

sg

sgg

sggE

<End Output

Create a complete class for your program named Rearrange Word and paste the entire class into the text box provided. Your class must contain a main method, and you should create at least two additional methods in your class to carry out the task described (one to reverse the word, the other to print out the reversed word in the pattern shown). Your program does not need to prompt the user for additional input beyond the first successful entry, it can simply terminate once the task has been completed.

import java.util.Scanner;

public class RearrangeWord {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        String input = "";
        do {

            System.out.print("Enter a word (at least four characters in length): ");
            String word = scanner.nextLine();
            String words[] = word.split("\\s+");
            input = words[0];
            if (input.length() < 4) {
                System.out.println("Word must be at least four characters in length, please try again. ");
            }

        } while (input.length() < 4);

        for (int row = 1; row <= input.length(); row++) {

            for (int col = input.length() - 1; col >= input.length() - row; col--) {
                System.out.print(input.charAt(col));
            }
            System.out.println();
        }

    }
}
