Try this:

String command = "cmd.exe /c c:\\testd\\testf.bat";

1) A string is automatically allocated when you put stuff in
double-quotes.
2) Batch files are not themselves executable; the command processor
(cmd.exe) is required to run them with the "/c" switch.

For a better understanding of Runtime.exec():
