How to swap two Integers without using a temporary variable in Java? One of the oldest trick questions from a programming interview is, How do you swap two integers without using a temp variable? This was first asked to me on a C/C++ interview and then several times on various Java interviews. The beauty of this question lies both in the trick to thinking about how you can swap two numbers without the third variable, but also problems associated with each approach. If a programmer can think about integer overflow and consider that in its solution then it creates a very good impression in the eye of interviewers.

How to check if File is Empty in Java? Example Tutorial One of the readers of my blog Javarevisited emailed me yesterday about how to check if a file is empty in Java and that's why I am writing this post to show that using an example. The common approach for checking if a file is empty or not is to first check if the file exists or notand then check if it contains any content, but Java has done that hard work for you. Well, it's pretty easy to check emptiness for a file in Java by using the length() method of the java.io.File class. This method returns zero if the file is empty, but the good thing is it also returns zero if the file doesn't exist. This means you don't need to check if the file exists or not.

Баг с псионическими сигнатурами в Java В классическом научно-фантастическом сериале BBC Доктор Кто часто используется следующий сюжетный приём: Доктору удаётся избежать неприятностей, показав удостоверение личности, которое на самом деле совершенно пустое. Разумеется, удостоверение сделано из специальной «психобумаги», заставляющей смотрящего на неё человека видеть то, что захочет Доктор: пропуск, ордер или что-то ещё. Оказывается, некоторые новые релизы Java тоже были подвержены подобному трюку в реализации широко используемых сигнатур ECDSA. Если запустить одну из уязвимых версий, то нападающий легко сможет подделать некоторые типы сертификатов SSL и handshake (что позволяет вмешиваться в обмен данными и модифицировать их), подписанные JWT, декларации SAML или id-токены OIDC и даже сообщения аутентификации WebAuthn. И для всего этого достаточно цифрового аналога чистого листа бумаги. Читать: https://habr.com/ru/post/670742/?utm_campaign=670742
