建造者模式 建造者模式為客戶端返回的不是一個(gè)簡(jiǎn)單的產(chǎn)品，而是一個(gè)由多個(gè)部件組成的復(fù)雜產(chǎn)品 角色 Builder抽象建造者 buildPartX getResult ConcreteBuilder具體建造者 Product產(chǎn)品角色 Director指揮者 復(fù)雜對(duì)象 指包含多個(gè)成員屬性的對(duì)象，它們稱為部件或零件 比如汽車(chē)，包含方向盤(pán)、發(fā)動(dòng)機(jī)、輪胎等

1.角色類

package Builder;/*** Created by e550 on 2016/10/1.*/ public class Actor {private String type; // 角色private String sex; // 性別private String face; // 臉型private String costume; // 服裝private String hairstyle; // 發(fā)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.角色構(gòu)造抽象類

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.角色構(gòu)造具體類，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("飄逸");} }

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("披肩長(zhǎng)發(fā)");} }

惡魔角色

package Builder;/*** Created by e550 on 2016/10/3.*/ public class DevilBuilder extends ActorBuilder{public void buildType() {actor.setType("惡魔");}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("光頭");} }

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.客戶端執(zhí)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("類型:" + actor.getType());System.out.println("性別:" + actor.getSex());System.out.println("面容:" + actor.getFace());System.out.println("服裝:" + actor.getCostume());System.out.println("發(fā)型:" + actor.getHairstyle());} }

執(zhí)行結(jié)果
類型:天使
性別:女
面容:漂亮
服裝:白裙
發(fā)型:披肩長(zhǎng)發(fā)
