My Java is in full Swing (pun intended). :P
I am learning core Java and advanced Java and planning to do SCJP (now OCJP).. So while searching for some dumps, I came across these links. The best resource for learning Java is Oracle's Java Tutorials. I downloaded it for offline reading. Some concepts like this keyword and details about Collections and Generics are important.
This awesome guy, Nitin has posted four pdf's dumps on his blog..
Another awesome guy, Abhilash Koneri has posted total 6 quizzes and their answers too. Also he has written some good stuff about practical implementation of Java code in FTP.
That is all for today.. Adios. :D
