JAVA設計模式之【建造者模式】

建造者模式
	建造者模式為客戶端返回的不是一個簡單的產品，而是一個由多個部件組成的復雜產品
	角色
		Builder抽象建造者
			buildPartX
			getResult
		ConcreteBuilder具體建造者
		Product產品角色
		Director指揮者
	復雜對象
		指包含多個成員屬性的對象，它們稱為部件或零件
		比如汽車，包含方向盤、發動機、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("披肩長發");
    }
}

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("發型:" + actor.getHairstyle());
    }
}

執行結果
類型:天使
性別:女
面容:漂亮
服裝:白裙
發型:披肩長發
