Добавление java.util.Optional в Java получило радушный прием и обеспечило более плавный код для методов, которые иногда могут возвращать
null значения. К сожалению, Optional часто злоупотребляли, в частности, его слишком часто использовали. Иногда я сталкивался с кодом, который использует Optional в случаях, когда нет явного преимущества перед непосредственным использованием null.Если при вызове кода используется Optional.ofNullable(T) для возвращаемого значения из метода, который он только что вызвал, это может предупреждать, что использование
Optional не дает никаких преимуществ перед обычной проверкой на null.Как и в случае со всеми« красными флажками», это не означает, что передавать возвращаемое значение из метода в
Optional.ofNullable(T) всегда плохо (фактически, это необходимо делать для API-интерфейсов, имеющим Optionalпараметр), но обычно этот подход используется, чтобы не предоставлять реального значения, вместо прямого использования возвращаемого значения и его проверки на null.Читать: https://habr.com/ru/post/582628/?utm_campaign=582628

Ускоряем pow
В этой статье я хочу поделиться несколькими нестандартными алгоритмами для быстрого возведения числа в степень, а также продемонстрировать их реализацию и сравнить их быстродействие в C++, C# и Java.
Сравнить точность алгоритмов можно прямо сейчас на этой странице.
В конце будет краткая памятка по тому, где и когда лучше применять какой из методов. При правильном выборе можно добиться увеличения скорости вычислений в 5 раз при погрешности ~1%, а иногда и вовсе без неё.
Ускорь мои степени!
