Cannot find Symbol Color.XXX in class color

Hi guys,

I'm not sure which part of the programm actually creates the error, but whenever I compile a programm where I've used e.g. labels with a specific color for the font, I get every single time since 1 month the same error message:

Compiliere C:\Dokumente und Einstellungen\Michael\Desktop\Javaeditor\Frame\methoden.java mit Java-Compiler

methoden.java:49:32: cannot find symbol

symbol : variable WHITE

location:class Color

textfield.setBackground(Color.WHITE);

^

The strange thing is that I wrote a simple programm where I used the same commands half a year ago on the same computer, and it worked perfectly!!

But since a month I get those errors without having done anything to the computer! I didn't install anything. It's an old notebook just for the java programming we're doing in school, that's why I don't need to install anything. By the way, the error appeared when I still had Java 5 installed. But even the complete deinstallation of the old java version and an update to the latest version couldn't solve the problem.

Can anyone help, please?

G黷en tag Michael,>programmprogram because this is an English forum ; ) Sorry, it was just a little joke.do you have import java.awt.Color; in the beginning of your java file ?plz, post the whole code and tell us what JDK or JRE are you using.

I got the files from my teacher at school. They say it's the JDK 6 and JRE 6 - Update 1. And i do have imported the java.awt.Color at the beginning of my file.

Here's the whole code, but don't tell me what I can do better about the code, I know it's nothing really good^^

Oh, and by the way, I imported all those files just to test if it would work better with having imported all of these, but it did not help at all.

import java.awt.*;

import java.awt.color.*;

import java.awt.event.*;
