原型模式深复制的例子

 public class Prototype implements Cloneable, Serializable {

     private static final long serialVersionUID = 1L;
     private String string;

     private SerializableObject obj;

     /* 浅复制 */
     public Object clone() throws CloneNotSupportedException {
         Prototype proto = (Prototype) super.clone();
         return proto;
     }

     /* 深复制 */
     public Object deepClone() throws IOException, ClassNotFoundException {

         /* 写入当前对象的二进制流 */
         ByteArrayOutputStream bos = new ByteArrayOutputStream();
         ObjectOutputStream oos = new ObjectOutputStream(bos);
         oos.writeObject(this);

         /* 读出二进制流产生的新对象 */
         ByteArrayInputStream bis = new ByteArrayInputStream(bos.toByteArray());
         ObjectInputStream ois = new ObjectInputStream(bis);
         return ois.readObject();
     }

     public String getString() {
         return string;
     }

     public void setString(String string) {
         this.string = string;
     }

     public SerializableObject getObj() {
         return obj;
     }

     public void setObj(SerializableObject obj) {
         this.obj = obj;
     }

 }

 class SerializableObject implements Serializable {
     private static final long serialVersionUID = 1L;
 }
