设计模式-原型模式

原型模式又称对象复制模式,浅拷贝的时候,一般采用Object类的clone()方法.

给出如下场景: 人做某种运动.

1.建立抽象类 人

2.建立抽象类 运动

3.建立场景管理类,通过管理类实现场景

java代码如下:

package com.liu.pattern6;public class Prototype {public static void main(String[] args) {// TODO Auto-generated method stubManager.play(new Man("张三","15"), new Run("跑步"));}}class Manager{public static void play(Person p,Activity a){Person p2 = (Person) p.clone();Activity a2 = (Activity)a.clone();System.out.println(p2.toString() + a2.toString());}}abstract class Person implements Cloneable {public Person(String name,String age){this.name =name;this.age = age;}private String name;private String age;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getAge() {return age;}public void setAge(String age) {this.age = age;}public Object clone(){try {return super.clone();} catch (CloneNotSupportedException e) {// TODO Auto-generated catch blocke.printStackTrace();}return null;}public abstract String toString();}class Man extends Person{public Man(String name, String age) {super(name, age);// TODO Auto-generated constructor stub}@Overridepublic String toString() {// TODO Auto-generated method stubreturn super.getName()+"("+super.getAge()+")";}}abstract class Activity implements Cloneable{public Activity(String name){this.name = name;}private String name;public String getName() {return name;}public void setName(String name) {this.name = name;}public Object clone(){try {return super.clone();} catch (CloneNotSupportedException e) {// TODO Auto-generated catch blocke.printStackTrace();}return null;}public abstract String toString();}class Run extends Activity{public Run(String name) {super(name);// TODO Auto-generated constructor stub}@Overridepublic String toString() {// TODO Auto-generated method stubreturn "在进行"+super.getName()+"的运动";}}

 

c#代码如下:

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace com.liu.pattern6{    class Prototype    {        static void Main(string[] args)        {            Manager.play(new Man("张三", "15"), new Run("跑步"));        }    }    class Manager    {        public static void play(Person p, Activity a){Person p2 = (Person) p.clone();Activity a2 = (Activity)a.clone();System.Console.WriteLine(p2.toString() + a2.toString());        System.Console.ReadKey();    }    }    abstract class Person {        private String _name;        private String _age;        public String Name{            set{                _name = value;             }            get{                return _name;            }        }        public String Age{            set{                _age = value;             }            get{                return _age;            }        }    public Person(String name,String age){    Name =name;    Age = age;    }    public Object clone(){            return base.MemberwiseClone();    }    public abstract String toString();    }    class Man : Person{    public Man(String name, String age):base(name,age) {    }    public override String toString() {    // TODO Auto-generated method stub    return base.Name+"("+base.Age+")";    }    }    abstract class Activity{        public Activity(String name){    Name = name;    }    private String _name;        public String Name {            set { _name = value; }            get { return _name; }        }    public Object clone(){            return base.MemberwiseClone();    }    public abstract String toString();    }    class Run : Activity{    public Run(String name):base(name) {    // TODO Auto-generated constructor stub    }        public override String toString()        {    // TODO Auto-generated method stub            return "在进行" + base.Name+ "的运动";    }    }}
