The code attached below works fine and prints true which is fine but I could not understand why there was no compilation error on the equals function while it was trying to access the private member of another object. Could you please help me understanding this,

The equals method is accessing private member on an instance of its own class. This is allowed. The members of the class have access to private members of objects of their own class...

Well, the private member is used within the class and it is allowed. There would have been compiler error if it would have been used outside the class.
