// Serialize to disk public class TestSerialize {public static void main (String [] args) {SerializeUtils. writeObject (new Ques1114 ());}}

// For version V2.0, modify the num value (the serialVersionUID remains unchanged) public class Ques1114 implements Serializable {private static final long serialVersionUID = 1L; public final int num; public Ques1114 () {num = 321 ;}}

// Deserialize public class TestDeserialize {public static void main (String [] args) {Ques1114 ques1114 = (Ques1114) SerializeUtils. readObject (); System. out. println (ques1114.num); // output value }}
