1抽象的产品

public interface PhoneInterface {
     void getPhoneName();
}

2具体化的产品

@Slf4j
public class OpPhone implements PhoneInterface{

    @Override
    public void getPhoneName() {
     log.info("取得oppo手机");
    }
}

@Slf4j
public class XmPhone implements PhoneInterface {
    @Override
    public void getPhoneName() {
        log.info("取得小米手机");

    }
}

3抽象工厂类

public interface Factory {
    PhoneInterface getPhone();
}

4具体工厂类

public class XmFactroy implements Factory{
    @Override
    public PhoneInterface getPhone() {
        return new XmPhone();
    }
}

public class OpFactory implements Factory{

    @Override
    public PhoneInterface getPhone() {
        return new OpPhone();
    }
}

5测试调用

public class TestClass2 {
    public static void main(String[] args) {
        PhoneInterface opPhone = new OpFactory().getPhone();
        PhoneInterface xmPhone = new XmFactroy().getPhone();

        opPhone.getPhoneName();
        xmPhone.getPhoneName();

    }

}
