Iteration is a process of using a loop to access all the elements of a sequence. Most of the time, we usefor loopto iterate over a sequence. But there are some times when we need to iterate over a sequence using a different approach. In those cases, we need to use aniterator. In ...

Another subtle difference between the twoforEach()methods is that Java explicitly allows modifying elements using the iterator. Streams, in contrast, should be non-interfering. Let’s look at removing and modifying elements in more detail. 4.1. Removing an Element Let’s define an operation that ...
1) Some day it might make a difference, for some iterator type, and I don't want to have to do something special for that type. 2) Personally I think the prefix operator more clearly expresses the intent: "increment it", as opposed to "use it and then increment". (...) http://...

I actually figured Iterator.toString(int) would consume most of the time. Which is part of the point really, that allocation and collection are so fast in Java, particularly with short-lived objects, that there's a good chance any performance difference between the two will be eclipsed by th...
