Display array of words in reverse order

I have some of my code already done I just do not know how I would display the sentence in reverse order than what is entered.
For example; if one enters "my name is joe"
It should display in the output: Joe
is
name
my

import java.util.Scanner;


public class Sentence {
public static void main(String [] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter a sentence: ");
String sentence = input.nextLine();

String[] words = sentence.split(" ");

// Display the array of words in
// reverse order
}
}

Answer

If I understand your problem, you can do something like that:

public static void main(String [] args) {
    Scanner input = new Scanner(System.in);
    System.out.print("Enter a sentence: ");
    String sentence = input.nextLine();
    String[] words = sentence.split(" ");
    for (int i = words.length - 1; i >= 0; i--) {
        System.out.println(words[i]);
    }
}
