合肥工业大学编译原理实验LR(1)文法分析，Scala实现；Java实现GUI。
Dell G3 3579；
OS：Ubuntu 16.04.06；
IDE：InterLRiJ IDEA Ultimate Edition（2019.1.3）；
编程语言：Scala、Java。
代码行数：
①纯粹自己写的、不含GUI代码、不含注释、不含空行：736；
②含参考而来的GUI代码与各类注释：1474；
数据结构与算法设计：
①核心代码部分，均为自己参照书上的算法，用极为朴素的方法实现（Scala，736）；
②GUI的编写参考“菊花侠”大佬的手笔，Java封装实现界面；
③界面还有待改进的地方，如：表格2可以加个滚动条。

图 3 分析界面
图 4 显示初始文法
图 5 分析完成（输入表达死为“i+i*i”）
图 6 分析完成（输入表达死为“i+i*i”，手动把单元格拉长了些）
