void cancelAll(Collection c) {
     for (Iterator i = c.iterator(); i.hasNext(); )        
        i.next().cancel();
}

Now with the new For-Each loop your code is extremely simplified, look at the same code but with the new syntax:

void cancelAll(Collection c) {    for (TimerTask t : c)        t.cancel();}

That is amazing. As the referenced web page states the new loop reads as “for each item of type TimerTask t in the c collection“. This is very streamlined and the best thing I like about this is Java is taking the good things from other languages and putting them into Java. This is what will make Java become even easier to use and more widely accepted in the programming world.
