Actually, yes, it is possible to bypass the constructor when you instantiate an object, if you use objenesis to instantiate the object for you . It does bytecode manipulations to achieve this. Deserializing an object will also bypass the constructor.
Read moreCan we create an object without constructor in C++?
Defining a class without a constructor but with a destructor is perfectly legal C++, but is not recommended. Your compiler will try to generate a default constructor for you, which will automatically call the default constructor of all members in your class.
