Question

I am having a problem.
I have a function to remove some files and then reboot the system. It contains a lot of files, so before the whole set of files are getting deleted, my reboot command is getting executed.

How can I solve this in my Java code.

To delete the files, I am using:

Runtime.exec("/bin/rm -rf /myDir");
Runtime.exec("/bin/shutdown -r now");

You can use the Process returned by exec and wait until it finishes:

Process p = Runtime.exec("/bin/rm -rf /myDir");
p.waitFor();
Runtime.exec("/bin/shutdown -r now");
