switch ('c') {
case 'c':
case 'C':
System.out.println("CCCCCCCCCCCCCCcccCCcc");
}我来科普一下
switch 语句的 BNF (https://github.com/antlr/grammars-v4/blob/master/java9/Java9.g4
switchStatement ::= SWITCH "(" expression ")" switchBlock
switchBlock ::= "{" [switchStatementGroup] [switchLabel] "}"
switchStatementGroup ::= switchLabels blockStatements
switchLabels ::= {switchLabel}
switchLabel ::= CASE constantExpression ":"
| CASE enumConstantName ":"
| DEFAULT ":"https://users-cs.au.dk/amoeller/dRegAut/JavaBNF.html 这有个奇特 BNF 的版本
表示起来更加优雅

The complexity of Git distracts attention from the software under development. A user of Git needs to keep all of the following in mind:
+ The working directory
+ The "index" or staging area
+ The local head
+ The local copy of the remote head
+ The actual remote head

反正我是在这张图( 复制粘贴命令,至于它如何工作以及背后的理念一知半解
我只知道 Git 提供了开分支,并行开发(pull/merge),保留历史和给历史打标签的能力,其他功能我都不重视

(其实 TeX 排版也不太复杂,就是个好玩的工具可以使用,不过由于排版支持功能很多还是需要专门学习的
(据说 TeX 可以用于装 B 所以学习(
(据说 LaTeX 是我不懂的名词
(因为学历不高所以不懂(笑)

某宝的那个 ID 设置真的恶心…设置好了不能改,默认的会自动填充到输入框…卡了一下戳了两次不小心戳到「保存」现在脑子里全是 MMP
