I have implemented the writeObject() and readObject() methods for the Dog class. The
line 53: I am passing the Dog object to writeObject() method. So it could somehow use the Dog reference and get access to the writeObject() that is overridden.
line 61: I am using the ObjectInputStream reference variable to call the readObject() method. I am casting it to Dog after the object is returned by readObject method.
How could the ObjectInputStream reference variable get access to a method that is available in Dog class. I am not passing the dog object as an argument to readObject.
Could someone help to understand the ObjectInputStream gets access to Dog's readObject() method.
1. No new object is created during de-serialization process, just already persisted object is read;
2. The virtual machine will automatically check to see if either method (i.e. readObject and writeObject) is declared during the corresponding method call. The virtual machine can call private methods of your class whenever it wants but no other objects can.
