Hey guys,
I have a program that I want to launch and pass a parameter. For example:
"C:\Program Files\aProgram\test.exe -login joeSmith password1"
The thing is I can't just add that to a shortcut because lots of other people will be using this computer as well. Is there a way of executing a program with parameters through java?
Thanks,
PO.
Jump to PostTake a look at the Runtime class. Although I have not tried it with parameters, I think all you have to do is give the entire command to execute to its exec() method …
Jump to PostI assume here you want to run the above command from java.
Java provides you with facilities to run commands at shell/prompt with theRuntime.exec()function
It should be something like this :String cmd = "C:\Program Files\aProgram\test.exe -login joeSmith password1"; Runtime run = Runtime.getRuntime(); Process …

Runtime run = Runtime.getRuntime();
Process proc = run.exec(cmd);Also see this (E.g. From Java Developer's Almanac)
alright thanks guys I will try this asap!
That worked great verruck and stephen!
Thanks for all your help!
By the way, you should be very wary of just making your program call Runtime.exec() and "sitting back and relaxing": if the other process logs anything out (to either the standard output or error stream), you must read the contents of those streams else things will generally freeze.
If you use a ProcessBuilder, you can call its redirectErrorStream() method so that you only have to read from one stream instead of two.
