Identifying last loop when using for each

Question

I want to do something different with the last loop iteration when performing \'foreach\' on an object. I\'m using Ruby but the same goes for C#, Java etc.

Answer 1

What you are trying to do seems just a little too advanced for the foreach-loop. However, you can use Iterators explicitly. For example, in Java, I would write this:

Collection ss = Arrays.asList("A","B","C");
Iterator it = ss.iterator();
while (it.hasNext()) {
    String s = it.next();
    if(it.hasNext())
        System.out.println("Looping: " + s);
    else 
        System.out.println("Last one: " + s);
}
