答题小软件
讲真这次的要求对现在的我来说难度是巨大的，GUI的编写还得到了同学的帮助，不然真心要GG，这次也花了七八个小时的时间，但做完之后也感觉的到自己的进步，看来真的是要多写代码。
课程理解：类图的3个基本组件：类名、属性、方法。其中类有6种关系：泛化，实现，依赖，关联，聚合，组合。
Dice.java
package touzi; import java.util.*; public class Dice { private int faceValue; public Dice(){ } public void Roll(){ Random random=new Random(); faceValue=random.nextInt(5)+1; } public int getFaceValue(){ return faceValue; } }

运行测试
开始是界面的显示，开始时是两个旋转的骰子
然后按抽取学生
如果回答正确的话抽取奖励
另外一个基于控制台的
课后小结：
学习到了关于界面的一些东西，虽然过程很痛苦，但结果应该是可喜的，希望自己能够再接再厉。
