Question: OK so I started with this:

```
import java.awt.*;
import java.applet.*;

public class Oval extends Applet {
    public void paint (Graphics g) 
    {
        g.setColor(Color.red);
        g.fillOval(50,50,70,70);
    }
}

```

Saved it as Oval.java. Then I ran javac Oval and it spits out the class file. Linked the class file to my HTML and all was good. Then I tried to change the color of the oval to say Color.blue and everything was not so good. I just changed the code in the Oval.java file, then re-ran the javac Oval and the result was a "new" class file... but it's the output is the exact same.

Do I have to "reset" the memory space or something? I have tried for some time to get the answer but I simply lack the vocabulary to accurately ask the question.

Answer: 
It could be that your browser is caching the previous version of your applet. Try clearing / disabling your cache.
Maybe the old version is in your browser-cache? Try hitting the follwing keys on your page:

* Windows: ctrl + F5
* Mac/Apple: Apple + R or command + R
* Linux: F5
