Java Warning Message
hello all, I have a problem with my program in java netBeans...
I created an IP monitoring program and there will be a "warning message" when there is a change of IP. This is a program that I created:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                       
        // TODO add your handling code here:
InetAddress minta= InetAddress.getLocalHost();
FileWriter fstream = new FileWriter("List_IP.txt");
PrintWriter out = new PrintWriter(fstream);
                }catch (IOException e){//Catch exception if any
                        System.err.println("Error: " + e.getMessage());

program detects the IP and then save the file "txt".
program runs automatically, and when the IP changes, the program will give "warning message". I was wondering how to make it .. anyone can help me? pleaseee ......

Re: Java Warning Message
make a daemon thread to monitor the change of IP
if any change that thread calls a the main program to notify of the change
