Performance Iterating Through A List In Java Stack Overflow, WEB Apr 15 2010 nbsp 8212 32 What I have learned is that using the get i in for loop will result in an iteration over the whole list over and over again each loop run Using an Iterator like enhanced for loop does will just move the iterator the the next list element without iterating the whole list again
Iterating Through A List In Reverse Order In Java
Iterating Through A List In Reverse Order In Java, WEB Mar 19 2015 nbsp 8212 32 One argument for doing so is that the for loop is much cleaner than keeping track of indexes or using an explicit iterator In about half the cases the list an ArrayList is being iterated in reverse order by using an index today
