a.

Explanation of Solution

Program:

File name: “Alphabetize.java”

//Import necessary header files

import java.util.*;

//Define a class named Alphabetize

public class Alphabetize

{

    //Define main method

    public static void main(String[] args)

    {

        //Declare the variables

        String str1, str2, str3;

        //Create an object for the Scanner class

        Scanner in = new Scanner(System.in);

        //Prompt the user to enter the first string

        System.out.print("Enter first string >> ");

        str1 = in.nextLine();
