策略模式,良好的扩展性,将对象分割成2部分,一部分是相同属性(抽象类),一部分是独有的属性(接口),良好的扩展,自由的组合出需要的新的对象
资料来自网络,例子由自己编写
例子: 角色和武器 角色都有攻击力 ,攻击速度和移动速度 武器有自己独有的特性 但是角色又拥有武器
定义角色的抽象父类
1 package org.masque.designpatterns.strategy; 2 /** 3 * 4 * Description: 5 * Player.java Create on 2014年7月5日 下午1:39:16 6 * @author masque.java@outlook.com 7 * @version 1.0 8 * Copyright (c) 2014 Company,Inc. All Rights Reserved. 9 */ 10 public abstract class Player { 11 12 protected int ATK; 13 14 protected double ASPD; 15 16 protected int speed; 17 18 protected Weapon weapon; 19 20 public int getATK() { 21 return ATK; 22 } 23 24 public void setATK(int aTK) { 25 ATK = aTK; 26 } 27 28 public double getASPD() { 29 return ASPD; 30 } 31 32 public void setASPD(double aSPD) { 33 ASPD = aSPD; 34 } 35 36 public int getSpeed() { 37 return speed; 38 } 39 40 public void setSpeed(int speed) { 41 this.speed = speed; 42 } 43 44 public Weapon getWeapon() { 45 return weapon; 46 } 47 48 public void setWeapon(Weapon weapon) { 49 this.weapon = weapon; 50 } 51 52 @Override 53 public String toString() { 54 return "Player [ATK=" + ATK + ", ASPD=" + ASPD + ", speed=" + speed 55 + ", weapon=" + weapon + "]"; 56 } 57 }
定义武器的接口:
1 package org.masque.designpatterns.strategy; 2 /** 3 * 4 * Description: 5 * Weapon.java Create on 2014年7月5日 下午1:39:16 6 * @author masque.java@outlook.com 7 * @version 1.0 8 * Copyright (c) 2014 Company,Inc. All Rights Reserved. 9 */ 10 public interface Weapon { 11 12 public void display(); 13 }
角色玩家:
1 package org.masque.designpatterns.strategy; 2 /** 3 * 4 * Description: 5 * Player01.java Create on 2014年7月5日 下午1:39:16 6 * @author masque.java@outlook.com 7 * @version 1.0 8 * Copyright (c) 2014 Company,Inc. All Rights Reserved. 9 */ 10 public class Player01 extends Player { 11 12 public Player01(int ATK,double ASPD,int speed,Weapon weapon){ 13 this.ATK = ATK; 14 this.ASPD = ASPD; 15 this.speed = speed; 16 this.weapon = weapon; 17 } 18 }
武器1:
1 package org.masque.designpatterns.strategy; 2 /** 3 * 4 * Description: 5 * Weapon01.java Create on 2014年7月5日 下午1:39:16 6 * @author masque.java@outlook.com 7 * @version 1.0 8 * Copyright (c) 2014 Company,Inc. All Rights Reserved. 9 */ 10 public class Weapon01 implements Weapon { 11 12 @Override 13 public void display() { 14 System.out.println("我是武器01"); 15 } 16 17 @Override 18 public String toString() { 19 display(); 20 return "Weapon01 []"; 21 } 22 }
武器2:
1 package org.masque.designpatterns.strategy; 2 /** 3 * 4 * Description: 5 * Weapon02.java Create on 2014年7月5日 下午1:39:16 6 * @author masque.java@outlook.com 7 * @version 1.0 8 * Copyright (c) 2014 Company,Inc. All Rights Reserved. 9 */ 10 public class Weapon02 implements Weapon { 11 12 @Override 13 public void display() { 14 System.out.println("我是武器02"); 15 } 16 17 @Override 18 public String toString() { 19 display(); 20 return "Weapon02 []"; 21 } 22 }
测试类:
1 package org.masque.designpatterns.strategy; 2 /** 3 * 4 * Description: 5 * MainTest.java Create on 2014年7月5日 下午1:39:16 6 * @author masque.java@outlook.com 7 * @version 1.0 8 * Copyright (c) 2014 Company,Inc. All Rights Reserved. 9 */ 10 public class MainTest { 11 12 public static void main(String[] args) { 13 Player01 player01 = new Player01(50, 0.65, 350, new Weapon01()); 14 System.out.println(player01); 15 16 player01.setWeapon(new Weapon02()); 17 System.out.println(player01); 18 } 19 }
player不需要知道Weapon具体的实现细节
java多态,player拥有的武器也能更换
