The concepts of fail-fast and fail-safe iterators emerged as relatively recent additions in Java, initially introduced alongside Concurrent Collections such as ConcurrentHashMap and CopyOnWriteArrayList in Java 5.Java Collections offer support for two distinct types of iterators: Fail-Fast iterators and ...
This means you could iterate and work with stale value, but this is the cost you need to pay for a fail-safe iterator and this feature is clearly documented Difference between Fail Safe and Fail Fast Iterator in Java In order to best understand the difference between these two iterators, yo...

Each data collection in Exonum storage supports a rich set of operations, such as iteration and O(1) clearing. Data migrations are a first-class entity for the database backend, which provides various helpers for them, such as automatically cleared temporary data storage and persistent iterators....

Java JavaScript use the same iterable in "for" statement again: Why? The root cause is in the __iter__() method. When it called, we should return an iterator with the internal position pointer reset to 0. Here is the corrected version of the code. ...
Class loaders in Java follow a hierarchical structure. The initial class is loaded through the assistance of the public static main() method declared in your class. Once the initial class is loaded and executed, subsequent classes are loaded by the classes that are already loaded and running wit...
C# has these great constructs built-in: Generics, partial classes, anonymous types, iterators, nullable types, static classes, delegate interface. Implicit types, object and collection initializers, auto-implemented properties, extension methods, query and lambda expressions, expression trees, partial meth...
What is .NET? Formally, .NET is “an open source developer platform, created by Microsoft, for building many different types of applications. You can write .NET apps in C#, F#, Visual C++, or Visual Basic.” Informally, .NET is the tool that lets you build and run C# programs (we’...
