抽象工厂模式

包结构如图

ps:理解起来会有些抽象

1.功能接口PlayGame.java

public interface PlayGame {
    public void game(); 
}

2.实现功能接口的两种设备Computer.java和Phone.java

public class Computer implements PlayGame{

    @Override
    public void game() {
        System.err.println("玩电脑游戏!!");
    }
}


public class Phone implements PlayGame {

    @Override
    public void game() {
        System.err.println("玩手机游戏");
    }

}

3.工厂接口FactoryTypeInterface.java

public interface FactoryTypeInterface {  
    public PlayGame playGameType();  
}

4.两种工厂ComputerPlayGameFactory.java和PhonePlayGameFactory.java

ps:两种工厂都实现工厂接口,实现方法相同,实现内容不同

/**
 * 工厂
 * @author 淹死的鱼o0
 */
public class ComputerPlayGameFactory implements FactoryTypeInterface {

    @Override
    public PlayGame playGameType() {
        // TODO Auto-generated method stub
        return new Computer();
    }

}

/**
 * 游戏工厂
 * 
 * @author 淹死的鱼o0
 */
public class PhonePlayGameFactory implements FactoryTypeInterface{

    @Override
    public PlayGame playGameType() {
        // TODO Auto-generated method stub
        return new Phone();
    }
}

5.测试:

public class PlayGameTest {
    @Test
    public void phonePlayGameTest() {
        FactoryTypeInterface typeInterface = new PhonePlayGameFactory();
        typeInterface.playGameType().game();
    }
    
    @Test
    public void computerPlayGameTest() {
        FactoryTypeInterface typeInterface = new ComputerPlayGameFactory();
        typeInterface.playGameType().game();
    }
}
