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

This compiles and runs perfectly fine on Windows. Any help would be much appreciated.

Answer 1

On ix operating systems like OSX ; is the command separator. Path separator is : .

So change to:

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