int i=10;
//i stores bit patern of 10(1010)
Dog d = new Dog();
But what d stores ?Is that mean d stores the memory location of (new Dog).As like pointers.

Java will not let you see that bit pattern, no matter how hard you try; there's no way to convert a reference into an int, as you can in C++. So it truly doesn't matter.

But yes, it's a pointer, or perhaps a pointer to a pointer (a "handle"), which allows for object movement and heap compaction.
