Execute .bat file when I press jMenuItem

[Radu]

I searched the net but I didn't find a solution for this problem. How can I execute .bat file when I press jMenuItem in NetBeans.

 private void ButonDownloadSActionPerformed(java.awt.event.ActionEvent evt) {
        //String TiparBat = "D:\\Radu\\Lucru\\Programare\\Test\\Tipar.bat";
        Runtime.getRuntime().exec("cmd /d start D:\\Radu\\Lucru\\Programare\\Test\\Tipar.bat");

    }

What happens when you try that code?

[Radu]

I get unreported exception java.io.IOException; must be caught or declared to be thrown
----
(Alt-Enter shows hints)

[Tolls]

That's because exec() throws an IOException, which you need to handle.

[Radu]

Is this OK?

try {
      String TiparBat = "D:\\Radu\\Lucru\\Programare\\Test\\Tipar.bat";
      Process p = Runtime.getRuntime().exec("D:\\Radu\\Lucru\\Programare\\Test\\Tipar.bat");
      p.waitFor();
      System.out.println(p.exitValue());
    }
    catch (Exception err) {
      err.printStackTrace();
    }

Does it work?

[Radu]

some kind of...

[Tolls]

Well, there you go.

It's generally recommended to catch the most specific exception, in this case IOException and not to use a "catch-all" for Exception. Also, if successful execution of the rest of the program depends on this code not throwing IOException, you should catch the IOException and throw an appropriate subclass of RuntimeException.
