This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
Hi, I wish to run a commandline command(eg: dir or cls) from my java program. How is this possible? I also wish to run another exe file from my program. I have tried the following code: Runtime r = Runtime.getRuntime(); Process p = r.exec("./rasmol"); But this doesn't seem to work, even if the exe is an excutable command from the commandprompt. Thanks, Regards Jyothsna.
Hi, This doesn't actually have anything to do with threads; I'm going to recommend that it be moved. First, as far as running rasmol goes: this code should work, given the right assumptions. Can you give any more details regarding what happens? Second, as to running commands like dir or cls: both of these are built into the "cmd" or "command" shell on Windows (which you have depends on the Windows version, of course.) Therefore, you have to run "cmd" and tell it to run the command:
Now, note that that output from this process won't go to the terminal but to a Java InputStream that you can read from; get it using p.getInputStream(). Also, I doubt that running "cmd /c cls" is going to do anything, but it might surprise you.
