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

If you already know, say, two OO programming languages already, sure. You can learn Java in three months. Actually, you should be able to get your way around the language in just one day.
Some of the basic skills that you should possess to be a Java developer are: Java is an effective language and it's really necessary to have a knowledge of the syntax to ace it. You can definitely learn the syntax in 20 days as the concepts are easy to grasp and it would be an advantage if you have learned other programming languages like C++ or C.

But to excel in Java or to learn data structures in it, it would take time.
Sun Certified Java Programmer by Kathy Sierra…. Honestly the best book if you would like to refresh your Java… If you look to start learning, Thinking in Java by Bruce Eckels is the best book….
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).
