原型模式：用原型实例指定创建对象的种类，并且通过拷贝这些原型创建新的对象。以下是例子：

//必须要实现 Cloneable ，调用clone()方法才不会抛出异常

public abstract class AbstractSpoon implements Cloneable{

String spoonName;

public void setSpoonName(String spoonName){

this.spoonName = spoonName; }

public String getSpoonName(){

return spoonName; }

public Object clone(){

Object object = null;

try{

object = super.clone(); }

catch(CloneNotSupportedException exception){

System.out.println("AbstractSpoon is not Cloneable"); }

return object; } }

 

public class SoupSpoon extends AbstractSpoon{  

public SoupSpoon(){

this.setSpoonName("Soup Spoon"); } }

 

//测试类 

public class Test {  

public static void main(String[] args) {

AbstractSpoon ss = new SoupSpoon();

SoupSpoon sss = (SoupSpoon) ss.clone(); } }
