If you can help me to do it

Hi everyone.
I'm new to Java and i want to be good at programming using java as i'm in C and C++.
I studied them 2years ago and from then i made a lot of projects using them till i'm now good at them.
I believe the best way to get good command of programming language is making projects .

I hope that someone more advance in Java tell me what are the best projects for a "New To Java" to try to improve our programming , i think these projects must be graduated in their level to improve his performance without being that simple or that difficult.

Thanks in advance to any one who participates in this post.
