+# 1.任务
+完成对冬奥会的赛事数据的爬取，并实现一个能够对国家排名及奖牌个数统计的控制台程序
+
+# 2.如何运行
+将OlympicSearch.jar放在与scr相同的目录下，将input.txt和output.txt放置于data文件夹中，以命令行参数传入读取文件和输出文件,在cmd中进入文件目录后输入`Java -jar OlympicSearch.jar input.txt output.txt`就可以运行程序
+
+## 指令
+```
+total //输出总将排榜
+schedule 0202//输出0202的赛程
+
+非法指令
+schedule  Error
+totol     Error
+schedule0202  Error
+schedule total   N/A
+
+```

221900115/codestyle.md

+# 1.标识符命名
+
+- 尽量都用英文来表示含义，能不使用拼音就不使用拼音
+- 对于一些局部变量会使用英文的缩写命名，如：计数变量 count 命名为 cnt，求和变量用 sum，中间值变量用 temp，最大值 max，最小值 min
+- 常量则使用全大写 MAX MIN
+- 函数名的命名使用为驼峰法，尽量使用动宾短语来明确意思如：读取 txt 文件的内容`readTxt(String path)`,读取 Json 文件的内容`readJsonFile(String path)`,输出奖牌榜`writeTotalRank()`
+- 再每个函数名开始之前会用//+功能注释说明函数用途
+
+# 2.大括号的位置
+
+- 在函数声明时左大括号附加再函数声明后，右大括号另起一行
+  例如
+
+```
+public static String readJsonFile (String fileName) {
+
+
+
+
+
+}
+
+```
+
+- 同样在条件语句和循环语句大括号的位置也这样放，
+
+```
+while (true) {
+
+
+
+
+}
+
+if (a==b) {
+
+
+
+
+}
+
+```
+
+# 3.空格及缩进
+
+- 使用 tab 键作为缩进
+- 二元运算符左右需要加空格`a + b`
+- 在 if，while 与（）之间要加上一个空格`if (a==b)`
+- 在两个函数声明之间需要空出一格
+
+```
+//输出每日赛程
+public static void writeDateSchedule (String path) {
+
+
+
+}
+
+//输出奖牌榜
+public static void writeTotalRank () {
+
+
+
+
+
+}
+```
+
+# 4.注释
+
+- 单行注释用//
+- 多行注释用/\* \*/
+- 在声明意义不明确的局部变量时加上单行注释//明确意义
