我是Java编程新手，一直在使用Windows的大学计算机。我是Mac用户，无法尝试在终端中编译。这些是我提出的错误：

-bash: MessageBoardServerV4.java: line 16: syntax error near unexpected token `('
'bash: MessageBoardServerV4.java: line 16: `        public Clock() { t = 0; }

这在Windows上编译并运行完美。任何帮助将非常感激。

在像OSX这样的操作系统上，;是命令分隔符。路径分隔符是:。

所以改为：

javac -cp json-simple-1.1.1.jar:. MessageBoardServerV4.java
