Executing a Command from Java and Waiting for the Command to Finish

Question

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.c         


        

Answer 1

The answer given is correct. I added that the window opened by the code needs to be closed manually.

Process p = Runtime.getRuntime().exec("cmd /C start /wait filepath.bat");
int exitVal = p.waitFor();

Answer 2

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();

Answer 3

calling "cmd /c start" causes cmd to fire off another instance and exit immediately. Try taking out the "start" command.
