Hello everybody! My name is Han and I am a beginner in Java en I bought the book 'head first java'. I really love the book, only I got a script(from the book page 384) here and it isn't working
It is supposed to be a simple animation, but java doesnt see the
PaintComponent function in the inner class, so i only get a square with a round on it.
I hope somebody can help me.

Hi,

Welcome to JavaRanch!

Looks basically OK to me, except that in the go() method you're constructing an instance of MyDrawPanel, but in the code the class is named MydrawPanel; as such, this won't compile. Perhaps you've got another MyDrawPanel.class lying around from a previous compilation?

Thanks for the response.
I am affraid not
Maybe a weird question, but why can't he take an instance of the innerclass?

When I run the code you have posted, I get a green drawing line downwards to the right.

Isn't it that was it expected to do??

Thank you for your response,
yes it is and that's strange, I only get a round shape that is getting
a different color for 130 times.

I have a feeling i'm doing something very wrong.
Maybe you or someone else know where the problem is?
Sorry i am completely new to Java.
