Hello,
I'm trying to get SCJP2 certification. Can anyone suggest a best way for learning and remembering Java API's such as java.lang, java.util, java.io etc. for the exam.

The way I see it is to write small applications. Not only will you be able to understand the API in a practical way, but you'll also have greater chances to remember them later. The learning-by-heart thing does not apply very well here. Take one package after another, one class after another and write small programs that shows you the concepts. Then, you can mix several concepts together and soon you'll begin to understand the API very well...
Don't hesitate to post your code here if you have trouble.
Good luck...
