Hi,
I have a question about one of the examples in the lesson "Tour of
java.lang.* and java.util.* classes". The example is about the
Process and Runtime classes. Here is the example program:
1 class RuntimeDemo {
2 public static void main(String args[]) {
3 Runtime rt = Runtime.getRuntime();
4 Process proc;
5 try {
6 proc = rt.exec("regedit");
7 proc.waitFor(); //try removing this line
8 } catch (Exception e) {
9 System.out.println("regedit is an unknown
10 command.");
11 }
12 }
13 }
When I ran the program, the Registry Editor appeared. i tried running
the program with and without the proc.waitFor() line, and did not
notice any difference between the programs. In both cases, the
Registry Editor appeared, and when I closed the editor, the program
stopped.
What should the different behaviors be for the two programs? I use
NetBeans 6.5. Thank you!
Jim Tarsi
