A x, u, v; // creating x,u,v reference variable of type A
x=new A(); // creating a new instance of class A and assigning it to reference variable x
A y=x; // assigning the instance x to another reference variable y of same type A
A z=new A(); // creating another instance of A and assigning to reference variable z
Therefore, only two instances of class A
are created.
