Need Tutorial on I/O and Thread

[yanrao]

Anybody can suggest some good and detailed tutorial for the part of I/O and Thread. I am currently using Complete Java2 Certification Study guild by Rob&Heller. Those two parts are not complete in that book. Thanks a lot for the help.

Take a look here:-
http://java.sun.com/docs/books/tutorial/essential/threads/index.html
for threads...
YOu will also find information there about IO, but IMHO it's not that good.

The book on Java Certification by Khalid is a very good book for these chapters.
