关于一个备忘录的课程设计...io输出部分
本人在做课程设计..想做一个备忘录...
现在把输入部分完成了..（不过有很严重的缺陷...请帮忙解决）
但是输出部分不会写，就是写到FileReader one=new FileReader("Memo.BOX");这里
想把文件里的东西按“发生日期 发生时间 发生事件”这样子分别在jtable中输出（个人觉得用io和字符串的知识就能够顺利输出了...）
但是这部分不会写.....能够请大家帮忙一下吗？
老师说用sql的部分能够写...但是上课完全没有学过sql的...大后天就交了..
后天还得出外做另一个课程设计..希望大家能帮忙一下..
无尽感激...
