This week's book giveaway is in the Testing forum. We're giving away four copies of Data Structures the Fun Way: An Amusing Adventure with Coffee-Filled Examples and have Jeremy Kubica on-line! See this thread for details.
The parsing of all command line arguments into the String is done by the shell (Command Prompt for Windows). You would need to change that in order to do what you want, but as far as I know that's not possible in Windows, and at the very least tricky on UNIX / Linux.
Sudheer's workaround would work - you turn all the separate command line arguments into one large argument (by quoting it; don't forget to escape any existing quotes). This will then be sent to the JVM as a single-element String to the main method. You can then do with it whatever you want.
