For example if a proxy is running on localhost at port 8080 then we can use:

Runtime.exec() is not a command line!
You cannot do starts, redirections, etc.

You can invoke start if you prefix it with cmd.exe, essentially then cmd.exe is the command and the rest are parameters. However why would you need to do start?
> To run the Windows command interpreter, execute either command.com or cmd.exe, depending on the Windows operating system you use. Listing 4.5 runs a copy of the Windows command interpreter and then executes the user-supplied command (e.g., dir).
Yes, you can do re-directions using the same trick mentioned above.
Actually the url you supplied gives the above solutions too.
