why dont we use pointers in java?

Answer 1

One of the reasons java doesn't have pointer is that, pointers are a way to hack(or attack) a system i.e they provide access to system resources. So removing pointers removes vulnerability to attack.

But implicitly there are pointers in Java. All objects are pointers. Because every object points to a location making it a pointer. But they can't be manipulated as in C.

Answer 2

Pointers don't exist in Java because that's one area of C Java tried to fix. Instead, Java crippled the programmer by taking pointers away.
