Hello Ranchers,

Want to know which superclass MAP extends ?
Want to know which superclass Collections hierachy extends?
Want to know why java does not support pointers?
Want know C++ is platform independent, so is java, then why Java is extensively used?

Please help me out.

Map & Collection are interfaces.

You probably want to invest in a good book to find the answers to these questions. Many people on this forum use the K&B book - from the nature of your questions I am guessing you are new to Java so you probably want to get an introductory guide first.

If you don't already, you should have a link to the Java API on your desktop or browser. Finding the answers to these questions is very quick and easy if you do.
