Using Split Method To Reverse A String

In this exercise, create a program that asks a user for a phrase, then returns the phrase with the words in reverse order. Use the String class's .split() method for this.

Example input
The rain in Spain falls mainly on the plain

Example output
plain the on mainly falls Spain in rain The

While I understand the assignment, nowhere in the text is it covered how to reverse the order of the words in the string. I understand using the .split method, but not for this exercise.

Here is my code so far.

import java.util.*;
/**
* Java class SplitString
* This program asks for a phrase, and the code allows the phase to return in reverse order.
*/

public class SplitString {
public static void main (String[] args){
//set phrase input and mixed which will be the result

[Code] ....

As you can see, I have been googling this method and have come up nearly empty. My text does not cover the .reverse() method. The only thing it covers with .split() is how to split a string. I also tried StringBuilder with no success.
