declaring objects in C++ vs java

Question

I have been using c++ for a while now and I am learning java,

declaring objects in java is confusing me,

In java we write

myclass myobject = new myclass();
myobject.mymethod();

Is it same as this code in c++ ?

myclass *myobject = new myclass();
myobject->mymethod();

i.e is the memory getting allocated on heap? If it is on heap why we never free the memory. I believe the new keyword is the same. If so, how do we allocate memory on stack?

Is it same as this code in c++ ?

Yes. It's the same.

Yes it.

If it is on heap why we never free the memory.

The object is allowed to garbage collector when it is no more reachable. i.e when there are no valid reference to that object or (de-referenced)

If so, how do we allocate memory on stack?

When the particular thread execution starts, variables related to that thread will be placed on stack and will be remove immediately once the job of that thread finished. Every thread has it's own stack.
