Why Java does not support pointers?

As per the design decision Java does not support pointers explicitly.This greatly reduces the burden of dynamic memory management while coding from programmers.Though programmers dynamically allocate memory while coding but they need not worry about deallocating this memory.The automatic garbage collection feature of Java collects dangling references of objects though it has a trade off on performance as programmer managed memory management will be efficient as compared to JVM driven automatic garbage collection.
