推荐答案

/ code>实际上是一个数字类型，包含unicode值（UTF-16，确切地说 - 你需要两个 char 表示字符外的字符）。你可以做一切，你可以做一个 int 。

char is actually a numeric type containing the unicode value (UTF-16, to be exact - you need two chars to represent characters outside the BMP) of the character. You can do everything with it that you can do with an int.

getNumericValue（）尝试将该字符解释为数字。

Character.getNumericValue() tries to interpret the character as a digit.
