Does hashcode number represent the memory address? [duplicate]

Question

I have learned that hashcode is a Unique Identification reference number, which is a hexadecimal number.
My doubt is, does the reference number represents the memory address of the object?

For example:

Employeee e1=new Employee();
System.out.println(e1.hashcode());

Will this code return me the memory address of my object?

Answer 1

Hashcode is not a unique identification. It's just a number that helps you distinguish objects. Two different objects may have the same hash code and it is fine.

HashCode characteristics:

1. If obj1 and obj2 are equal, they must have the same hash code.
2. If obj1 and obj2 have the same hash code, they do not have to be equal.
