Google Webtool Kit (GWT)

Java Script, a powerful script for dynamic web application development. Basically, i don't like to use java script for websites development because the process is tedious and error-prone process, developers can spend 90% of their time working around for those non productive errors.

@Override annotation

After back from New Zealand, this the first time i officially used Java 5 and above to do coding, it is bit hard for me to code in Java 5, because i am not familiar with the Java 5 new features such as annotation, generics , boxing unboxing those stuffs.
