In my Java program, I create a process that executes a command to run a batch file like this:
try {
File tempFile = new File("C:/Users/Public/temp.cmd");
tempFile.createNewFile();
tempFile.deleteOnExit();
setContents(tempFile, recipe.getText()); //Writes some user input to file
String cmd = "cmd /c start " + tempFile.getPath();
Process p = Runtime.getRuntime().exec(cmd);
int exitVal = p.waitFor();
refreshActionPerformed(evt);
} catch (InterruptedException ex) {
Logger.getLogger(mainFrame.class.getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(mainFrame.class.getName()).log(Level.SEVERE, null, ex);
}
Now, what I would like to have happen is that the command
refreshActionPerformed(evt);
runs only after the batch file I called has finished executing. But right now, it runs immediately after the Command Prompt opens.
How do I fix this?
I manged to find the answer elsewhere. To keep the initial process open until the batch file finished all you need is "/wait"
Process p = Runtime.getRuntime().exec("cmd /C start /wait filepath.bat");
int exitVal = p.waitFor();
