Java设计模式-构造者模式

实体类

package factorymode.simplefactory.builder;
public class MobilePhone {
    //手机屏幕
    private String screen;
    //电池
    private String battery;
    //话筒
    private String microphone;
    //听筒
    private String phoneReceiver;
    //机身
    private String phoneBody;
    public String getScreen() {
        return screen;
    }
    public void setScreen(String screen) {
        this.screen = screen;
    }
    public String getBattery() {
        return battery;
    }
    public void setBattery(String battery) {
        this.battery = battery;
    }
    public String getMicrophone() {
        return microphone;
    }
    public void setMicrophone(String microphone) {
        this.microphone = microphone;
    }
    public String getPhoneReceiver() {

    }

        this.phoneBody = phoneBody;
    }
    @Override
    public String toString() {
        return "MobilePhone{" +
                "screen='" + screen + '\'' +
                ", battery='" + battery + '\'' +
                ", microphone='" + microphone + '\'' +

                ", phoneBody='" + phoneBody + '\'' +
                '}';

建造者接口

package factorymode.simplefactory.builder;
public interface IBuildPhone {
    /**
     * 建造手机屏幕
     */
    void buildScreen();
    /**
     * 建造手机电池
     */
    void buildBattery();
    /**
     * 建造手机听筒
     */
    void buildMicrophone();
    /**
     * 建造手机话筒
     */
    void buildPhoneReceiver();
    /**
     * 建造手机机身
     */
    void buildPhoneBody();
    public MobilePhone build();
}

IPhoneX 建造者

package factorymode.simplefactory.builder;
public class IPhoneX implements IBuildPhone {
    private MobilePhone mobilePhone;
    public IPhoneX() {
        mobilePhone = new MobilePhone();
    }
    @Override
    public void buildScreen() {
        mobilePhone.setScreen("OLED");
    }
    @Override
    public void buildBattery() {
        mobilePhone.setBattery("2700");
    }
    @Override
    public void buildMicrophone() {
        mobilePhone.setMicrophone("listen");
    }
    @Override
    public void buildPhoneReceiver() {
        mobilePhone.setPhoneReceiver("receiver");
    }
    @Override
    public void buildPhoneBody() {
        mobilePhone.setPhoneBody("body");
    }
    @Override
    public MobilePhone build() {
        return mobilePhone;
    }
}

指导者

package factorymode.simplefactory.builder;
public class Director {
    public MobilePhone createMobilePhone(IBuildPhone iBuildPhone) {
        iBuildPhone.buildBattery();
        iBuildPhone.buildMicrophone();
        iBuildPhone.buildPhoneBody();
        iBuildPhone.buildPhoneReceiver();
        iBuildPhone.buildScreen();
        return iBuildPhone.build();
    }
}

测试类

package factorymode.simplefactory.builder;
public class Builder1 {
    public static void main(String[] args) {
        Director director = new Director();
        MobilePhone phone = director.createMobilePhone(new IPhoneX());
        System.out.println(phone);
    }
}
