I just took my SCJP 1.4 exam, and though I passed, I truly realized how uninformed i am about threads, and I would love to learn. As I am currently very very poor, and out of a job, I can't afford any books. I was wondering if anybody has any suggestions about websites that teach threads. I am going through the Sun site already, and it is alright. But I am looking for some variety that's all. Any help would be appreciated.
