Hi

This is slightly out of topic (to say the least) but
could someone help me on this?

How can I pass a command at the dos prompt? I tried
the following code but it only works for windows
commands. I want to send a command like "copy x.txt
x.java" or something as a string value whose
parameters will be set at runtime. I am showing the
static method of my class file. Here, the copy
statement doesn't work but notepad gets opened.

Thanx in advance
Vijay

public static void main(String args[])
        {
        try {
        Runtime r = Runtime.getRuntime();
        r.exec("copy t1.java t2.java");
        r.exec("c:\\windows\\notepad.exe");
        System.out.println("Hi");
        }catch(IOException e) {System.out.println(e);}
        }
