Print words with pre in them java

Create a class StringDemo that contains the following static methods:
•	A method that takes in a sentence, tokenises it using a single space, and then prints only the words that start with "pre".
•	The main method where you declare 2 variables and initialise them to sentences of your choice; then test the method that you have defined in previous step using the 2 sentences.

import java.util.ArrayList;
public class StringDemo{
	public static void main(String... args){
		String S1 = "We love prefix	 that have car strongly wheels and car seats";
		String S2 = "I have a lovely designed car that has many car features beautifully and the car has a good car";

		printWordsWithPre(S1);
		printWordsWithPre(S2);

		System.out.println(printWordsWithPre(S1));
		System.out.println(printWordsWithPre(S1));

	}
//-	Tokenises a string/sentence and prints only the words that end with ly.
	public static void printWordsWithPre(String str){
		String[] sTokens = str.split("\\p{javaWhitespace}");
		for(int i = 0; i < sTokens.length; i++){
			if(sTokens[i].endsWith("pre")){
				System.out.println(sTokens[i]);
			}
		}
	}
