Question

I just came across the following code:

for(Iterator<String> iterator = stuff.iterator(); iterator.hasNext();) {
   ...
}

This strikes me as a sort of misuse of a for… Wouldn’t this code be better as:

Iterator<String> iterator = stuff.iterator();
while(iterator.hasNext()) {
   ...
}

?

Any specific reasons anyone can think of to use the for? Which is the better approach?

Answer 1

What is stuff? Can you apply enhanced for loop for it?

for (String str : stuff) {
   doSmth (str);
}

The only reason to use iterators explicitly is to remove certain elements while looping with iterator.remove().
