TAMING THE TIGER – JAVA 5 IN PRACTICE

Gone are the days when Java was considered a toy language for creating web games, trying to catch up to its big brothers C and C++. Now Java is everywhere, database interactions, financial domains, e-commerce, and you name it. Please look at Java 1.5, code named Tiger. It is also known as Java 5. Seems more like a completely new product than the revision of an old language. Tiger is full of dramatic and innovative changes to what you know as simply Java.

This session is built in such a way as to provide those fundamental knowledge in refactoring, designing reusable components, programming to interfaces, design patterns and some tips and tricks so that you can immediately go back and apply to your systems if you have not done so yet. The session would be suiting to those future Java programmers to get equipped with the latest trends and principles in designing and architecting efficient Object Oriented Systems.

I am going to provide a learning exercise on the use of Tiger, with some coding examples. The tutorial is structured as below:-
