Java... hmmm

Suddenly, I feel the need to learn the Java language. I have no idea why, but then I just want to try it out. Maybe make one Java application for my phone. I tried it once, but it didn't turn out too good. So now, I'm trying again. Since I'm quite okay with the C# programming language that I'm currently using now, it shouldn't be too hard to adapt to Java. Both of them have almost the same syntax. Gosh, now I have to download more stuff...
