Using the loop condition to break the loop makes this piece of code
much more complex and probably also less efficient.

Maybe, but I still find it clearer, and easier to debug.

Amazing. It would never occur to me that (below) is clearer or easier
to debug than (above). But obviously people are very different.

    public Integer findIt(Integer n) {
        Iterator<Integer> iter = myInts.iterator();
        Integer i = null;
        boolean found = false;
        while(iter.hasNext() && !found) {
            i =;
            found = (n == i);

        return found ? i : null;
