I recommend reading through the Sun's tutorials for code examples and practice in all areas of Java programming, especially the areas you wish to improve in.
Depending on how much of beginner examples you were looking for, check out CodingBat for some good beginner exercises. Project Euler is another good site, but depending on your skill level now, this may be too much, but it's worth trying anyways.
Most importantly, Its also worth noting that personal projects are a great way to start to learn a new language. I would also recommend starting a project that is benefical to you and get cracking right away, no time is better than the present!
