序列化一个类对象，并将其反序列化为另一类

Question

Do everybody know if in Java exist possibility to serialize MyClass object and deserialize it as MyAnotherClass object?

MyClass object has fields as below:

public class MyClass implements Serializable {

 private String text;
 private int number;
 private String abbrv;

}

And MyAnotherClass :

public class MyClass implements Serializable {

 private String text;
 private int number;
 private String abbrv;
 private boolean b; 
 private List<String> myList;

}

If it's possible, please tell me how to do that.

Answer 1

You can if the originally serialized object's class contains a

private Object readResolve()

method, or if it contained a

private Object writeReplace()

method prior to serialization, or if you use a trusted subclass of ObjectInputStream that suitably overrides resolveObject(), or a trusted subclass of ObjectOutputStream that overrides replaceObject().
