Hi Everyone! I have seen many posts from people who passed the new version of SCJP stating that there are many questions on multiple synchronized methods in a single thread/multiple threads. There is also mention of effects of synchronized & non-synchronized methods in same thread. If everyone can contribute some examples on this type in this post itself... or links to such a tutorial etc... it would be very nice... as we will get all of resources in this one post... aslo we can be better prepared. The new exam also asks a lot on IO. Marcus has put a really nice revised tutorial on IO on www.jchq.net My request to all the gurus... please contribute. Thnaks a lot in advance... thanks a lot.
