程序執行截圖:
開始界面(第一次進入有提示輸入用戶名)
提示輸入題量:
修改背景顏色:
若輸入的值超過5或小於1,則會出錯:
出題界面:
輸入答案:
提交答案,顯示統計界面:
开发环境：Eclipse，js，css，html
程序完成的方向：
1.可以出表达式里含有负整数（负整数最小不小于-100）的题目，且负数需要带括号，用户输入的结果不用带括号。如： 2*（-4） = -8。
2.用户答题结束以后，程序可以显示用户答题所用的时间。
3.用户可以选择出题的个数（最多不能超过5个题目），答题结束可以显示用户答错的题目个数和答对的题目个数。
4.用户在第一次答题时，需要用户输入用户名，用户下次启动后，程序需要记住用户前一次输入的用户名 。
5.程序可以出单个整数阶乘的题目：如：4!=24。
6.程序可以设置答题时间，时间设置为整数，单位为秒，最大不能超过120秒，若超过了答题时间未答题，则提示：时间已到，不能答题。
7程序可以设置皮肤功能，可以改变界面的颜色即可。

预计用时7天，实际用时6天。
分工：我：编写主要核心算法。 我的小伙伴：界面的设计排版，提供思路，测试排除错误。
總結:
由於時間比較趕,技術還不過關,勉強做出了一點功能,
其中
1.階乘功能已經做出,但是還未嵌入.
2.用戶輸入有效性還沒測試.
3.括號式子功能還沒弄出來.
4.java裏面很多沒用的功能和參數或對象都還沒來得及清理出來..請諒解下哈..第一次做想做的模式,不再是java或者C那些了(笑
以上是這次作業的成果.還有很多要改善的地方,請加分.謝謝!!有很多不足的地方,還望指教~!
