Real life example of iteration

[fam2315]

I need a little help with an assignment, to come up with a real-world example of iteration, and how it can be achieved recursively.

I was thinking of someone looking for something inside of a box, maybe a specific item:

public boolean containsItem(){
Iterator itr = Box.contents().iterator;
Object myItem = paper;
while(itr.hasNext()){
item i = itr.next();

if (i == myItem){
return i;
}
} 

return false

}

Would you consider this to be a good real iteration example?

One problem is the code shouldn't compile. One return is of an int another of an item.
Another is that the item to be tested for should be passed to the method vs created in the method.
