Intellij长“整数值太大"但在 long.maxvalue 的范围内 [英] Intellij long "integer value is too big" but in range of long.maxvalue

问题描述

这可能是一件愚蠢的事情，但是编译器怎么可能在 Long.Max = 9223372036854775807 时显示这个?

This might be a silly thing but how is this possible that compiler will show this while Long.Max = 9223372036854775807 ?

推荐答案

Java 中必须有 Long 字面量以 L 结尾，并添加 L 到您的整数将纠正您的问题，如下所示:Long s = 9223372036854775806L

You must have Long literals in Java ending with an L, adding an L to your integer will correct your issue, like so: Long s = 9223372036854775806L

这是因为默认情况下 Java 将所有整数解释为 32 位 (int)，后缀 L 确保您的整数被解释为 64 位.

This is because by default Java interprets all integers as 32-bit (int), the suffix L ensures that your integer is interpreted as 64-bit.
