Collections framework.

Can some one tell me the relation between equals(),== and hashCode().
I would also like to know a link for studying collections and if possible a link for questions on this topic.
Thnks.

The "hashCode contract" is discussed in the API under Object's hashCode method. Let us know if that clears it up.

Can you please give the link.

As Marc mentioned, the "hashCode contract" is discussed in the API under Object's hashCode method. So a quick look at JavaDoc --> Object class --> hashcode() yields....

You will want to bookmark the main index page...

http://java.sun.com/j2se/1.5.0/docs/api/index.html

...and refer to it often.

You'll need the Java API documentation very often when you're programming in Java. You can look it up on Internet everytime you need it, but you can also download it and put it on your own computer, so that you can also access it when you have no Internet connection.

On the JDK 5 download page scroll down to "J2SE 5.0 Documentation". Click the button on the right of that to download the documentation, and unzip the ZIP file on your computer after downloading.
