10 Things You Didn’t Know About Java


10 Things You Didn’t Know About Java

So, you’ve been working with Java since the very beginning? Remember the days when it was called “Oak”, when OO was still a hot topic, when C++ folks thought that Java had no chance, when Applets were still a thing?
I bet that you didn’t know at least half of the following things. Let’s start this week with some great surprises about the inner workings of Java.

1. There is no such thing as a checked exception

That’s right! The JVM doesn’t know any such thing, only the Java language does.
Today, everyone agrees that checked exceptions were a mistake. As Bruce Eckel said on his closing keynote at GeeCON, Prague, no other language after Java has engaged in using checked exceptions, and even Java 8 does no longer embrace them in the new Streams API (which can actually be a bit of a pain, when your lambdas use IO or JDBC).

Java навсегда! 12 причин длительного доминирования Java


Java foreverЛегко забыть значимость технологии, как только она пронесется кометой через коллективное сознание и погаснет огненной смертью за горизонтом. К примеру, Cobol — когда-то этот язык был культовым для целой эпохи, а сейчас его можно сравнить разве что с протухшей рыбой. В наши дни любой хипстер-программист вам отчеканит, что Cobol – это полный отстой, старый и бесполезный язык. Java может стать следующей жертвой «актуальных» суждений.

Пик продаж книг по Java – далеко в прошлом. Матерые Java-утилиты уже не достаточно сексуальны для обложек журналов. Java уже 19 лет, а прогрессивные разработчики увлечены такими моднейшими и актуальнейшими технологиями как Node.js, Objective-C, Dart, Go и т.д., удивляясь: «Java? Этот артефакт эпохи Web 1.0 еще жив?»

Беглый поиск на Dice.com показывает, что работы на Java — навалом. Если для iOS около — 2500 предложений, для Java — более 17000. Конечно, нельзя всецело полагаться на эти цифры. Но тот факт, что на Dice.com рынок работы на Java потенциально в семь раз больше, чем для моднейшей iOS, говорит о том, «старина Java» чувствует себя довольно таки неплохо.
