使用原型实例指定要创建对象的类型,通过复制这个原型来创建新对象。
类图
实现
public abstract class Prototype{
abstract Prototype myClone();
}
public class ConcretePrototype extends Prototype{
private String filed;
public ConcretePrototype(String filed){
this.filed = filed;
}
@Override
Prototype myClone(){
return new ConcretePrototype(filed);
}
@Override
public String toString(){
return filed;
}
}
public class Client{
public static void main(String[] args){
Prototype prototype = new ConcretePrototype("abc");
Prototype clone = prototype.myClone();
System.out.println(clone.toString());
}
}
运行结果
abc
