Java 中支持多少个数组维度，例如 [1][1][1][1]....[1]? [英] How many array dimensions are supported in Java like a[1][1][1][1]....[1]?

问题描述

Java 中像 a[1][1][1][1]....[1] 支持多少个数组维度?我可以为数组声明无限数量的维度吗?

How many array dimension is supported in Java like a[1][1][1][1]....[1]? Can I declare an unlimited number of dimensions for an array?

推荐答案

数组维数限制为 255.

The number of array dimensions are limited to 255.

有趣的是，JLS定义的Java编程语言并没有这样的限制，但是你可以在JVM 规范，数组维度存储在 1 个字节中.

The interesting thing is that there is no such limitation in Java programming language defined by JLS, but you can see in the JVM specification, that the array dimension is stored in 1 byte.

但是，您在日常开发中几乎无法满足此限制.:-)

However, you can hardly meet this limitation on your day-to-day development. :-)
