InJavaprogramming, the termsfail fastandfail safeare opposite iterator types. An iterator in Java is an object that can be used to loop through collections and retrieve elements. The terms work the same way in programming as they do in project management. When a fail fast iterator encounters ...
Fail Fast vs Fail Safe Iterator in Java By: Rajesh P.S.When multiple threads are concurrently iterating over a collection, if one of the threads alters the structure of the collection during the iteration process, it is referred to as Concurrent Modification. This occurrence triggers the ...
Java Collections supports two types of Iterator, fail safe and fail fast. The main difference between a fail fast and fail safe Iterator is whether or not the underlying collection can be modified while its begin iteration. Fail safe Iterator allows that while fail fast Iterator doesn't, they ...
Interfaces:The abstract data types are referred to as interfaces in Java. They allow Java collections to be manipulated in a way that is not tied to the specifics of their representation. The Set represents the sorted collection of elements. In addition, object-oriented programming languages form...

From Swift 1.2 onwards we have three ways of performing typecasts: as is used for typecasts that will always succeed (e.g. someString as NSString), as? is used for typecasts that might fail (e.g. someView as? UIImageView), and as! is used to force typecasts. If you use as!
When you sort number, there are fast sorting algorithms and there are fast sorting algorithms. But this one is really fast. I can't say much more about it except for the fact that its fast and compact51,chexer.zipAs Jonathan wrote, "This is a tool I wrote to use in DevStudio to ...
