java如何使用预定义的甲板类制作Black Jack游戏
所以在课堂上我们必须学习ArrayBag课程，我相信你们都知道。如果不是的话，互联网上到处都是。无论如何，我们的项目是把它变成一个黑杰克游戏。然而，我不知道如何做到这一点。我想做一个卡片类，一个甲板类，然后是黑杰克类。然而，我再一次不知道如何将其实现到Array bag类中。谁来帮忙！到目前为止，我将为我所拥有的添加代码

//I will will keep T because its the norm, but i really don't want to.

bag= tempBag;
}// end constructor

this(DefualtItemCapacity);
} // if nothing, call DefualtItemCapacity, dont have to check for null if we overload the method
// thank you eclipse, for creating the methods from the interface :)
