Answer 1

To my opinion, the four most prominent enhancements since Java 1.4.2 are

• Generics
• enums
• enhanced for-loop and
• Annotations

There are a lot of additional classes and API enhancements, but if you want to ‘upgrade’ your code, I’d suggest to start your refactoring with using generics and replacing standard for loops by enhanced for loops. Both can be done without major code changes, clean up the code (you can delete a lot of lines of code) and improve readability. And using generics might reveal some hidden bugs 😉
