Question

1. Print the two strings in alphabetical order. Assume the strings are lowercase. End with newline. Sample output:

capes rabbits

import java.util.Scanner;

public class OrderStrings {
   public static void main (String [] args) {
      Scanner scnr = new Scanner(System.in);
      String firstString;
      String secondString;

      firstString = scnr.next();
      secondString = scnr.next();

      /* Your solution goes here */

   }
}

2. Write an if-else statement that prints "Goodbye" if userString is "Quit", else prints "Hello". End with newline.

import java.util.Scanner;

public class DetectWord {
   public static void main (String [] args) {
      Scanner scnr = new Scanner(System.in);
      String userString;

      userString = scnr.next();

      /* Your solution goes here */

   }
}

import java.util.Scanner;

public class OrderStrings {
    public static void main (String [] args) {
        Scanner scan = new Scanner(System.in);
        String firstString;
        String secondString;

        firstString = scan.next();
        secondString = scan.next();

        if(firstString.compareTo(secondString) < 0){
            System.out.println(firstString+" "+secondString);
        }
        else{
            System.out.println(secondString+" "+firstString);
        }
    }
}
