JAVA books- help

Hi everyone!


I would need your help.

My boyfriend is going to have his B-day soon. He is an BSc. ICT and he loves to programm, he owns a company, software projects and stuff, he loves Android too. I am not that much into understanding everything he does. So before we went to our holidays he wanted to buy some Java book, but we didnt have time.

Anyways, my question is, can anyone help me to deside which Java book should I buy for him as a B-day gift?


Thanks!

What is his skill level in Java? Does he want to make a game, 2D, 3D? There's alot of different books you can get for many different things.

Hm,no, not games... maybe this will help Bachelor Thesis: Using Android in Industrial Automation, Open Source Android USB-Oscilloscope its his thesis...
