    Default Display a variable in exception catch

    Hi,

    (new to java) I want to be notified when my box has no longer access to internet. The below test code works but it only returns a variable when I can ping a site, otherwise, it doesn't return anything.

    How can I get the "false" feedback from said code?

    TIA

    HTML Code:
    package ping;
    
    import java.io.IOException;
    import java.net.InetAddress;
    
    public class Ping {
    
        public static void main(String[] args) {
    
            InetAddress address;
            String test = "";
    
            try {
                address = InetAddress.getByName("www.google.com");
    
                boolean reachable = address.isReachable(5000);
    
                test = String.valueOf(reachable);
    
                System.out.println(test);
                
            } catch (IOException e) {
                System.out.println(test);
            }
    
        }
    }

    How can I get the "false" feedback
    What is a "false" feedback?

    Where does the feedback come from?

    How do you get any "feedback" with the posted code?

    Sorry, did not explain myself well.

    When my PC has access to internet (pinging google), the System.out.println(test) prints "true".
    When there is no connection to internet, how do I get System.out.println(test) print "false"?

    Set the value of test to "false"
