package Nov2016;import java.io.Serializable;// V1.0版public class Ques1114 implements Serializable{    private static final long serialVersionUID = 1L;    public final int num;    public Ques1114(){        num = 123;    }}

// 序列化到磁碟public class TestSerialize{    public static void main(String[] args) {        SerializeUtils.writeObject(new Ques1114());     }}

// V2.0版 修改num值（serialVersionUID保持不變）public class Ques1114 implements Serializable{    private static final long serialVersionUID = 1L;    public final int num;    public Ques1114(){        num = 321;    }}

// 還原序列化public class TestDeserialize{    public static void main(String[] args) {        Ques1114 ques1114 = (Ques1114)SerializeUtils.readObject();        System.out.println(ques1114.num);  // 輸出值    }}

今日問題： 
通過20161111問題知道還原序列化時final屬性會重新計算值，那這裡請問“輸出”處輸出結果是什嗎？（點擊以下“【Java每日一題】20161114”查看20161111問題解析）
