difference between statica and instance members

[person]

wat r the differences between these 2, and how are they used differently, and in which scenarios should each one be used in?

Static methods are associated with the class itself. One can call a static method without creating an object of the class. Non-static methods are associated with objects of that class, and can only be called by objects.

I suggest you take a look at wtd's An Introduction to Java, with particular attention to the second post
