Ok, so what happens when you do this.
A a1=new A();
A a2=new A();
A a3=new A();
I upload two pictures on how I imagine it being like. Can you
new A()
will call the no param constructor of class A and will create a new memory object.
A a1=new A(); // new memory object created
A a2=new A(); // new memory object created
A a3=new A(); // new memory object created
There are three different objects that are getting created, so the SECOND picture is true.
For the FIRST picture to be true, the declaration of references should be something like this:
A a1=new A(); // new memory object created
A a2=a1; // a2 points to the same memory object as a1 does
A a3=a1; // a3 points to the same memory object as a1 does
Here only one object(new used only once) is created but all the three references point to it.
