Java简单工厂模式

TV:

public abstract class TV {
    public abstract void play();
}

HaierTV:

public class HaierTV extends TV{

    @Override
    public void play() {
        System.out.println("This is HaierTV!");
    }
    
}

HisenseTV:

public class HisenseTV extends TV{

    @Override
    public void play() {
        System.out.println("This is HisenseTV!");
    }
    
}

TVFactory:

public class TVFactory {
    public static TV produceTV(String brand){
        if(brand.equalsIgnoreCase("HaierTV")){
            return new HaierTV();
        }else{
            return new HisenseTV();
        }
    }
}

TVFactory:

public class SimpleFactory {

    
    public static void main(String[] args) {
        TV tv_1 = TVFactory.produceTV("HaierTV");
        TV tv_2 = TVFactory.produceTV("HisenseTV");
        tv_1.play();
        tv_2.play();
    }
    
}

Result:

This is HaierTV!
This is HisenseTV!
