Deep copy "Object" type [duplicate]

Question

I have an object with a member of type "Object":

class MyObject{
    Object member;

    public Object getObject(){
        return member;
     }

     public void setObject(Object obj){
         member = obj;
     }
}

Is it possible to deep copy MyObject?

Answer 1

In its current implementation it is impossible because member can be anything and you cannot make a copy of what you dont know.

Answer 2

Implement Cloneable marker interface and you can copy of MyObject by clonning.

class MyObject implements Cloneable {
    public Object clone(){
      try {
        return super.clone();
      } catch (CloneNotSupportedException e) {
           return null; 
      }
   }
}

Members also need to be Cloneable other wise it will throw CloneNotSupportedException. ...

MyObject obj = new MyObject();
MyObject obj1 = obj.clone();
