For creating an object, interface does not contain the body of its abstract methods. Hence compiler does not have enough data for creating an object out of it.
On the other hand you can create a variable of that interface with any other class implementing that interface.
E.g. A is an interface and B is a class implementing A.
Now if you create
A obj = new A();
This statement wont give an implementation of methods inside A.
But,
class B implements A{
}

A obj = new B();
Here class B will be defining all the abstract methods inside interface A.
Hence it is not possible to create an object of interface but you can create a variable of it.
