其實物件的深克隆還可以通過序列化來實現，直接上程式碼，物件使用的還是之前的sheep物件，但是要實現Serializable的介面：

public class Client3 {
    public static void main(String[] args) throws CloneNotSupportedException, Exception {
        Date date = new Date(12312321331L);
        Sheep s1 = new Sheep("少利",date);
        System.out.println(s1);
        System.out
 
.println(s1.getSname());
        System.out.println(s1.getBirthday());


//      使用序列化和反序列化實現深複製
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        ObjectOutputStream    oos = new ObjectOutputStream(bos);
        oos.writeObject(s1);
        byte[] bytes = bos.toByteArray();

        ByteArrayInputStream  bis = new
 
 ByteArrayInputStream(bytes);
        ObjectInputStream     ois = new ObjectInputStream(bis);

        Sheep s2 = (Sheep) ois.readObject();   //克隆好的物件！

        System.out.println("修改原型物件的屬性值");  
        date.setTime(23432432423L);

        System.out.println(s1.getBirthday());

        s2.setSname("多利"
 
);
        System.out.println(s2);
        System.out.println(s2.getSname());
        System.out.println(s2.getBirthday());


    }
}
