1) MyObject foo;
foo object of type is created on stack (memory of size sizeof(MyObject) is allocated on stack.
2) MyObject *bar;
pointer of type MyObject class is created which is pointing to some unknown location.
3) MyObject *foobar = new MyObject();
memory is allocated on heap.

First one is just an object of MyObject named foo.
Second one is a pointer to the object of MyObject.
Third one creates an object of MyObject and points the variable to that object.

Easy One :-

1> Object foo of class type MyObject is being created on the stack.
2> Pointer named bar is being created which can point to the object of the type MyObject.
3> Here object of the class MyObject is being created on the heap.

1.object will create as a local variable
2. pointer of object will create as a local variable
3.pointer of object will create as a local variable and it is pointing to object which is created in heap.

only first one is correct.....
because object itself is a reference variable....
and moreover java doesn't support pointer(*)
