Java tutorials - Basic Help - Simple graphics

I am completley new to developing applications on Phones, I've managed to do the Hello World example from nokia.

I have a Nokia 7650 and am using the J2ME Wireless toolkit 2.0.

I'm after a few tutorials, simple, I've doen java before but have forgot most of it, its coming back to me.

At the moment i'm thrilled to see HelloWorld on my phone, I'd like to now just draw a simple square on the screen. Any tutorials or a tad bit of code?

Help get me started.

Thanks

😊
