Ok I'm a VERY (stress the VERY) beginner programmer and I made a yahtzee game. Now, I'm trying to make a high score list so as to keep track of the high scores in my 1-player yahtzee game even after the applet is closed. I have one class called Yahtzee that runs my game of Yahtzee, and I would like to be able to access another class that would take care of keeping the high scores (possibly through writing to a text file or something). I have looked all over the internet, and every way I find to write to a text file only works in a stand-alone program, and fails as soon as I try to access it through my yahtzee program. I know my coding sucks, but here is my main Yahtzee class (I won't show my dieRoll, scoreCard, and ruleTest classes because I don't think there necessary for what I'm trying to do)

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public class Yahtzee extends JApplet implements ActionListener

	dieRoll die1, die2, die3, die4, die5;
	JCheckBox check1,check2, check3, check4, check5;
	JLabel s1, s2, s3, s4, newline, newline2, newline3;
	scoreCard scorer;
	testRules tester;
	JButton roll, submit;
	public void init ()

		die1 = new dieRoll (20);
		die2 = new dieRoll (95);

And yes I know its not great but, oh well, if theres any way for me to do it let me know.

If you make a new class that holds your high scores and it implements java.io.Serializable, you can easily write it to a file and recover it intact later on; this takes out the mess of reading and parsing a file.
