program help: Extracting words from a string

[toad]

I need to write a program that extracts words from a string using spaces and punctuation marks as delimiters. The string needs to be entered from an input dialog box.

I am lost on this one.

import java.util.*;
import javax.swing.JOptionPane;

public class Exercise8_17 {
    /**Main method*/
        public static void main(String[] args) {
        // Receive text entered from the dialog box
        String s = JOptionPane.showInputDialog(
        "Enter a sentence using punctuation:");
        String delims = "[ .,?!]+";
        String[] tokens = str.split(delims);
        
        
        
        
        		
		System.out.println("The extracted words are:");
	}
}

This is what I have so far. Am I close.
