Java - How to refresh knowledge? (2 years ago)

Question

I have my first ever interview for a Java developer role, specifically RMI, Serverlets and JDBC.

However, it has been a while (2 years) since I have done any Java coding. I am sure I still have it up there somewhere and I do remember the Java syntax

I wanted to ask how can I re-fresh everything in 2-3 days specially the OOP concepts (polymorphism, inheritance) specifically to Java?

Any links, references and tutorials appreciated.

I am new to this site and I see there is a preference for programming related questions, hope I can get away with this!

Would also appreciate those that know any Java interview questions so I can go through them and test myself.

Thanks all

Answer 1

I'd suggest you you test yourself, e.g. on Java Black Belt, which has a good question base grouped by categories and detailled explanations for your mistakes.

I'd also recommend (re-)reading Sun's Java Tutorial and (longer) Thinking in Java by Bruce Eckel (3rd edition is free to download).

Answer 2

Tutorials on RMI

Java Servlet Technology

JDBC Tutorials

OOP concepts (polymorphism, inheritance): Head First Design Patterns

Answer 3

How about this. Take a certification guide. It will save you a lot of time, and give you an exercise after every chapter (might give you some interview questions). You don't need to bore you down to death by teaching yourself in a wordy way, what you might already know. The best would he Khalid's Java Certification Guide. Believe me it would be faster and more effective. Plus give you the skills for appearing in the test for real, if you like to. :)
