Learning java on daily basis

i'm so fuck*d up learning java!, soo hard!!! its like a total new concept than visual basic or anything like PHP!

its giving me a headache, but little by little im having a hang of it! which is nice that i know im improving...

i wanted to join a project with other java programmers but im afraid i cant be of any useful, but still i wanted to join to improve my knowledge on the language... any help would be appreciated, thanks
