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;

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。
