Question

how use Runtime.getRuntime().exec()?

I try:

try {
    String[] callAndArgs = {"path\\program.exe","arg1","arg2","arg3"}
    System.out.println("before");
    Process p = Runtime.getRuntime().exec(callAndArgs)
    System.out.println("in");
    p.waitFor();
    System.out.println("after");
} catch (IOException e) {
            System.out.println("catch io: " + e.getMessage());
        } catch (InterruptedException ie) {
            System.out.println("catch ie: " + ie.getMessage());
        }

And program doesn’t work. Output:

before
in
after
