建造者模式    建造者模式为客户端返回的不是一个简单的产品，而是一个由多个部件组成的复杂产品    角色        Builder抽象建造者            buildPartX            getResult        ConcreteBuilder具体建造者        Product产品角色        Director指挥者    复杂对象        指包含多个成员属性的对象，它们称为部件或零件        比如汽车，包含方向盘、发动机、轮胎等

1.角色类

package Builder;/*** Created by e550 on 2016/10/1.*/
public class Actor {private String type; // 角色private String sex;  // 性别private String face; // 脸型private String costume; // 服装private String hairstyle; // 发型public void setType(String type) {this.type = type;}public void setSex(String sex) {this.sex = sex;}public void setFace(String face) {this.face = face;}public void setCostume(String costume) {this.costume = costume;}public void setHairstyle(String hairstyle) {this.hairstyle = hairstyle;}public String getType() {return this.type;}public String getSex() {return this.sex;}public String getFace() {return this.face;}public String getCostume() {return this.costume;}public String getHairstyle() {return this.hairstyle;}}

2.角色构造抽象类

package Builder;/*** Created by jim on 2016/10/3.*/
abstract class ActorBuilder {protected Actor actor = new Actor();public abstract void buildType();public abstract void buildSex();public abstract void buildFace();public abstract void buildCostume();public abstract void buildHairstyle();public Actor createActor() {return actor;}
}

3.角色构造具体类，英雄角色

package Builder;/*** Created by e550 on 2016/10/3.*/
public class HeroBuilder extends ActorBuilder{public void buildType() {actor.setType("英雄");}public void buildSex() {actor.setSex("男");}public void buildFace() {actor.setFace("英俊");}public void buildCostume() {actor.setCostume("盔甲");}public void buildHairstyle() {actor.setHairstyle("飘逸");}
}

天使角色

package Builder;/*** Created by e550 on 2016/10/3.*/
public class AngelBuilder extends ActorBuilder{public void buildType() {actor.setType("天使");}public void buildSex() {actor.setSex("女");}public void buildFace() {actor.setFace("漂亮");}public void buildCostume() {actor.setCostume("白裙");}public void buildHairstyle() {actor.setHairstyle("披肩长发");}
}

恶魔角色

package Builder;/*** Created by e550 on 2016/10/3.*/
public class DevilBuilder extends ActorBuilder{public void buildType() {actor.setType("恶魔");}public void buildSex() {actor.setSex("妖");}public void buildFace() {actor.setFace("丑陋");}public void buildCostume() {actor.setCostume("黑衣");}public void buildHairstyle() {actor.setHairstyle("光头");}
}

4.角色控制器

package Builder;/*** Created by e550 on 2016/10/3.*/
public class ActorController {public Actor construct(ActorBuilder ab) {Actor actor;ab.buildType();ab.buildSex();ab.buildFace();ab.buildCostume();ab.buildHairstyle();actor = ab.createActor();return actor;}
}

5.客户端执行

package Builder;/*** Created by e550 on 2016/10/3.*/
public class Client {public static void main(String args[]) {ActorBuilder ab;ab = new AngelBuilder();ActorController ac = new ActorController();Actor actor;actor = ac.construct(ab);System.out.println("类型:" + actor.getType());System.out.println("性别:" + actor.getSex());System.out.println("面容:" + actor.getFace());System.out.println("服装:" + actor.getCostume());System.out.println("发型:" + actor.getHairstyle());}
}

执行结果
类型:天使
性别:女
面容:漂亮
服装:白裙
发型:披肩长发
