Swathireddy,

There are 2 major reasons for it.
1. Java is designed to develop GuI application software and not to write driver programs.
2. Handling pointers is different in different platforms. And mostly the memory locations where OS stores its critical information (used to write drivers) varies from OS to OS highly. This will make the programs OS dependent violating the actual intension of Sun which is to make configuration independent system.

Along with these, Java architects felt that handling pointers is very difficult and it does not balance the advantage they give. Thats why they removed pointers from Java.

Thanks,
Krishna
