Introduction

To stop the serialization of objects of your class, add writeObject() and readObject() methods in your class.

These methods should simply throw an exception. 

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

class NotSerializable implements Serializable {
  private void readObject(ObjectInputStream ois) throws IOException,
      ClassNotFoundException {
    // Throw an exception
    throw new IOException("Not meant for serialization!!!");
  }

  private void writeObject(ObjectOutputStream os) throws IOException {
    // Throw an exception
    throw new IOException("Not meant for serialization!!!");
  }

  // Other code for the class goes here
}
