抽象工厂设计模式

public interface IPhoneFactory {
    public void start();
}

public interface IComputerFactory {
    public void start();
}

public interface IProuductFactory {
    public IComputerFactory createComputer();
    public IPhoneFactory createPhone();
}

public class HuaweiPhone implements IPhoneFactory{
    @Override
    public void start() {
        System.out.println("华为手机开机");
    }
}

public class HuWeiComputer implements IComputerFactory{
    @Override
    public void start() {
        System.out.println("华为电脑开机");
    }
}

public class HuaWeiFactory implements IProuductFactory{
    @Override
    public IComputerFactory createComputer() {
        return new HuWeiComputer();
    }

    @Override
    public IPhoneFactory createPhone() {
        return new HuaweiPhone();
    }
}

public class Test {
    public static void main(String[] args) {
        IProuductFactory huaWeiFactory=new HuaWeiFactory();
        IPhoneFactory huaweiPhone=huaWeiFactory.createPhone();

    }
