your console is an application, in windows it is cmd.exe, under linux it would just be another shell, so you could use the same method to run other programs if you like... dont have any code so this is from memory and will probably need googling to correct:
create a Process object
get hold of the runtime object associated with the current java application.
call the exec method of the runtime object passing the application name as an argument.
e.g.
Code:
Process pr = Runtime.getRuntime().exec("cmd.exe")
so if you replaced cmd.exe with notepad it would hopefully fire up notepad or something like that.
good luck
