Write a program that prompts the user to enter three cities and displays them in ascending order. Here is a sample run: Enter the first city: Chicago Enter the second city: Los Angeles Enter the third city: Atlanta The three cities in alphabetical order are Atlanta Chicago Los Angeles

import java.util.Scanner;

public class SortStrings3 {

   public static void main(String args[]){

       Scanner scanner = new Scanner(System.in);

       String str1, str2, str3;

       System.out.print("Enter the first city: ");

       str1 = scanner.nextLine();

       System.out.print("Enter the second city: ");

       str2 = scanner.nextLine();

       System.out.print("Enter the third city: ");

       str3 = scanner.nextLine();

       System.out.print("The three cities in alphabetical order are ");

       if(str1.compareTo(str2) < 0 && str1.compareTo(str3) < 0){

           System.out.print(str1+" ");

           if(str2.compareTo(str3) < 0){

               System.out.print(str2+" ");

               System.out.println(str3);

           }

           else {

               System.out.print(str3+" ");

               System.out.println(str2);

           }

       }

       else if(str2.compareTo(str1) < 0 && str2.compareTo(str3) < 0){

           System.out.print(str2+" ");

           if(str1.compareTo(str3) < 0){

               System.out.print(str1+" ");

               System.out.println(str3);

           }

           else {

               System.out.print(str3+" ");

               System.out.println(str1);

           }

       }

       else{

           System.out.print(str3+" ");

           if(str1.compareTo(str2) < 0){

               System.out.print(str1+" ");

               System.out.println(str2);

           }

           else {

               System.out.print(str2+" ");

               System.out.println(str1);

           }

       }

   }

}

EXPLANATION:

Okay, we are given that a program should be written which will make user to enter three cities namely Atlanta, Chicago and Los Angeles (which should be done in ascending  alphabetical order).

So, we will be writting the code or program with a programming language known as JAVA(JUST ANOTHER VIRTUAL ACCELERATOR).

We will make use of java to write this program because Java can be used in Loading code, verifying codes and executing codes on a single or multiple servers.

The code or program can be seen in the attached file/document. Kindly check it.

i think so.
