java 接口实现防盗门功能

Door；

package locker;

public abstract class Door {
    public abstract void open();
    public abstract void close();
}

Lock:

package locker;

public interface  Lock {
void lockUp();//开锁
void openLock();
}

Security:

package locker;

public class Security extends Door implements Lock {
    @Override
    public void lockUp() {
        System.out.println("关锁");
    }

    @Override
    public void openLock() {
        System.out.println("开锁");
    }

    @Override
    public void open() {
        System.out.println("门开了");
    }

    @Override
    public void close() {
        System.out.println("门关了");
    }

}

Test；

package locker;

public class Text {
    public static void main(String[] args) {
        Security door = new Security();
        door.close();
        door.lockUp();
        door.openLock();
        door.open();
    }
}
