Javaargs

This is the java version of the Args program described in: http://butunclebob.com/ArticleS.UncleBob.CleanCodeArgs

public class ArgsMain { public static void main(String[] args) { try { Args arg = new Args("l,p#,d*", args); boolean logging = arg.getBoolean('l'); int port = arg.getInt('p'); String directory = arg.getString('d'); executeApplication(logging, port, directory); } catch (ArgsException e) { System.out.printf("Argument error: %s\n", e.errorMessage()); } }

private static void executeApplication(boolean logging, int port, String directory) { System.out.printf("logging is %s, port:%d, directory:%s\n",logging, port, directory); } }

Schema:

• char - Boolean arg.
• char* - String arg.
• char# - Integer arg.
• char## - double arg.
• char[*] - one element of a string array.

Example schema: (f,s*,n#,a##,p[*]) Coresponding command line: "-f -s Bob -n 1 -a 3.2 -p e1 -p e2 -p e3
