My thoughts as an enterprise Java developer.

Friday, April 07, 2006


I often see code like:
Iterator i = list.iterator();
while(i.hasNext()) {
but I write that (when Java 1.5 isn't available) as:
for(Iterator i = list.iterator();i.hasNext();) {

  • It 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? Which is better?
