原型模式又稱(chēng)對(duì)象復(fù)制模式,淺拷貝的時(shí)候,一般采用Object類(lèi)的clone()方法.

給出如下場(chǎng)景: 人做某種運(yùn)動(dòng).

1.建立抽象類(lèi) 人

2.建立抽象類(lèi) 運(yùn)動(dòng)

3.建立場(chǎng)景管理類(lèi),通過(guò)管理類(lèi)實(shí)現(xiàn)場(chǎng)景

java代碼如下:

package com.liu.pattern6;public class PRototype {	public static void main(String[] args) {		// TODO Auto-generated method stub		Manager.play(new Man("張三","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 block			e.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	}	@Override	public String toString() {		// TODO Auto-generated method stub		return 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 block			e.printStackTrace();		}		return null;	}		public abstract String toString();}class Run extends Activity{	public Run(String name) {		super(name);		// TODO Auto-generated constructor stub	}	@Override	public String toString() {		// TODO Auto-generated method stub		return "在進(jìn)行"+super.getName()+"的運(yùn)動(dòng)";	}	}
