DeSerialization

[Harikrishna Gorrepati]

Hi, This is from Whizlabs. Which line of the commented lines at Line#16 or 17 allow Question11_Ask objects to be correctly serialized and de-serialized

import java.io.IOException;
import java.io.ObjectOutputStream;
import java.io.Serializable;

public class Question11_Ask implements Serializable {

    private int x;
    public int getX() {
	return x;
    }
    public Question11_Ask(int x) {
	this.x = x;
	
    }
    private void writeObject(ObjectOutputStream s) throws IOException {
	//s.writeInt(x)
	//s.defaultWriteObject()
    }
}

Serialization is not on the SCJP objectives anymore...

[Trivikram Kamat]

public void defaultWriteObject() throws IOException
Write the non-static and non-transient fields of the current class to this stream. This may only be called from the writeObject method of the class being serialized. It will throw the NotActiveException if it is called otherwise.

From Java API of defaultWriteObject method in ObjectOutputStream

+1. Even I did not encounter any question related to serialization.

You never know..Sun may change the topics at any time. Also, Objectives may differ from one center to another center. Drag and Drop questions issue(s) are reproducable in some centers only. Some folks may be interested to take SCJP 5.0 exam. So, in any case, suggestions to these kind of questions would be really helpful.

Sun may change the topics at any time. Also, Objectives may differ from one center to another center.

Objectives are not changed very frequently. Exam objectives are only changed after a lot of considerations. It is true that some of the prometric centers don't update very fast, but serialization was removed from the objectives more than a year ago and its very very unlikely that anyone will face Serialization questions on the exam...
