alright. had posted this a while back in the Q&A thread but to no help. ive been assigned this programe and need to submit the source code for the same, he's also asked me to use applets. i have no prior experience with java and its not possible for me to catch up with so little time left. her is the problem.

Write a programe to read the contents of a 10 MB file and write it to another file and find out the process times taken for these read and write operations.

any help would be greatly appreciated. thanks a lot.

^^ The best way would be to pick a nice book.
I would suggest J2ME Complete Reference or Beginning J2ME: From Novice to Professional.
