Iterate with for loop or while loop?
for-loop, iterator, java
Solution
I prefer the for loop because it also sets the scope of the iterator to just the for loop.
Problem
I often see code like: ``` Iterator i = list.iterator(); while(i.hasNext()) { ... } ``` but I write that (when Java 1.5 isn't available or for each can't be used) as: ``` for(Iterator i = list.iterator(); i.hasNext(); ) { ... } ``` because - It is shorter - It keeps `i` in a smaller scope - It reduces the chance of confusion. (Is `i` used outside the while? Where is `i` declared?) I think code should be as simple to understand as possible so that I only have to make complex code to do complex things. What do you think?
