Problems That Are Driving Me Insane...

[Cloakd]

Hello all, i have recently been coding a little 2D game to get back into JAVA coding as i haven't done it for about a year and i keep stumbling on problem after problem. My first very simple build of the game worked fine but now that i have tried to implement a highscore system into it the whole thing has shut down, it wont load in browser and now not even in netbeans. Any help or advice would be greatly appreciated as this is driving me crazy.

The Errors i get when trying to run in Netbeans:

java.lang.InstantiationException: javaapplication2.Main
        at java.lang.Class.newInstance0(Class.java:340)
        at java.lang.Class.newInstance(Class.java:308)
        at sun.applet.AppletPanel.createApplet(AppletPanel.java:785)
        at sun.applet.AppletPanel.runLoader(AppletPanel.java:714)
load: javaapplication2/Main.class can't be instantiated.
        at sun.applet.AppletPanel.run(AppletPanel.java:368)
        at java.lang.Thread.run(Thread.java:619)

Here are all my classes, some are from an old highscore system im working off and others are being currently used in my new system.

New System uses:
Main.java
Ball.java *
Player.java *
Score.java *
FileReader.java
ScoreComparator.java

* these classes are all fine so i wont put in post but if needs be i can post them.
** (EDIT: I have now put in all the .java classes for you to see.

Again any help or advice would be greatly appreciated.
Kind regards,

Yea, i'd really like those other classes cause without those pretty much all the code is showed red as wrong because my program doesn't find those classes :s
If you don't like to post your whole program into the world wide web then post em to:
wimdeclercq@hotmail.com (if you're mailing, that scores.dat file might also be interesting , otherwise i'll create it myself.)

[Cloakd]

Scores.dat is just an empty File and i have just edited the post with all the classes.

[oxano]

to run it you create a new main, then call init() then start()?

[Cloakd]

no offence but the run(); command and the init(); command are allready implamented so that was no help atall.

bump?

He was asking you a question, trying to verify what was supposed to happen.
