Answer / venkatesh
reference will act as variable to point an object. Instead
of giving direct memory location(using pointers)to the
programmer java internally converted them into references,
so that java can avoid memory leaks and increase performance
in accessing object.

Answer / siri
As Pointers are not safe and secure which allows us to increament or decreament the memory locations such that we can reach the O.S related files.
So to avoid such insecurities we go with Reference Varaibles where we can't increament or decrement memory location of an object.Even if we try to print the address of the object it prints some hash code

Answer / seema yadav
The reference variable is useful in OOP because it permits the manipulation of objects by reference, and eliminates the copying of object parameters back and forth. It is also important to note that reference can be created not only for built_in data types but also for user defined data types such as structures and classes
