Comment on Java Internet connection checker by Andrzej

The method getDefaultInstance is not thread-safe. It should synchronized.

public synchronized static InternetChecker getDefaultInstance() {
if (ref == null) {
ref = new InternetChecker();
}
return ref;
}

Now it’s true Singleton :)

I need help, how to keep this running.. Mine only runs once when I start my program.

I decreased time to 1 * 60 * 1000

That should run every minute.

I’m just learning JAVA ..

thanks

Nice post man.
We can use listener pattern with this code to
fire connection status change to its listeners.
