A pointer is a variable which can hold the address of another variable or object. But, Java does not support pointer due to security reason.

  1. Memory access by the pointer is fundamentally unsafe. As if the pointers are available then a hacker can easily reach the main memory and can harm the application.
  2. Pointers causes a memory leak. Allocating and deallocating the pointers causes the formation of the array, quickly and immediately freeing the memory when no longer required. However, it can cause a memory leak when you were assigning a value to a pointer, WITHOUT freeing the previous memory. Garbage collection is your responsibility.

Java do not use pointers because using pointer the memory area can be directly accessed, which is a security issue. pointers need so memory spaces at the runtime. to reduce the usage of memory spaces java does not support pointers. and also pointers take more time at the run time
