See Sachidananda Patnaik there are so many implementation of pointer in prospect of c++ language. I think your question is in regards to java, even if is not , i would just like to inform you one of prospect as in java program we use API in java right all this are made of by the implementation C/C++. As far as pointer is concern see every byte in the computer's memory has a address and a value. These are occupied when you write any program to in order to deal with these address you implement pointer. It makes your functions more powerful with different scope.

C++ is an Object Oriented Programming Language is as we know , perfectly backword compatible with C. Becase of this backword compatibility .. it has got many flaws in it that prevented it to become a really good OOP language. Java was developped by keeping this point in mind . In java we cant find pointers and many other thing which may cause problems to the developped software system.I will demonstrate the flaw in C++ that occured by providing the programmer with grabbing addresses and accessing every memory location, with this simple example.class confidential{ private : int secret_code; public : confidential(int s=0) { this.secret_code = s; } void get_data(int x) { this.secret_code = x; } void display(void) { cout << "The secret code is : " <secret = 888; c.display();return 0;} So , this type of pointer usage in C++ prevented it to provide security to the data members inside an object. But , we cant find such problems with java .
