List an Array of Strings in alphabetical order

Question

I have a program which has the user inputs a list of names. I have a switch case going to a function which I would like to have the names print off in alphabetical order.

public static void orderedGuests(String[] hotel) {   //?? } 

I have tried both

Arrays.sort(hotel); System.out.println(Arrays.toString(hotel)); 

and

java.util.Collections.sort(hotel);

Weird, your code seems to work for me:

import java.util.Arrays;  public class Test {     public static void main(String[] args)     {         // args is the list of guests         Arrays.sort(args);         for(int i = 0; i < args.length; i++)             System.out.println(args[i]);     } } 

I ran that code using "java Test Bobby Joe Angel" and here is the output:

$ java Test Bobby Joe Angel Angel Bobby Joe
