Um, why would you want to since it pretty much defeats the purpose of writing a program in Java? Is there really no Java based way to do what you want?

you can use exec command.

Process processName=r1.exec("command");
processName.waitFor();

I don't remember what you have to import but the command is "exec":

e.g:

Runtime r=Runtime.getRuntime();
Process processName=r.exec("command");
processName.waitFor();//if you want to wait for it
