如何在Java Character类中表示空字符 [英] How to represent empty char in Java Character class

问题描述

我想在Java中将空字符表示为String中的"" ...

I want to represent an empty character in Java as "" in String...

像char ch = an empty character;

实际上，我想替换字符而不留空格.

Actually I want to replace a character without leaving space.

我认为了解这意味着什么可能就足够了:没有字符甚至没有空格.

I think it might be sufficient to understand what this means: no character not even space.

推荐答案

您可以分配'\u0000'(或0). 为此，请使用 Character.MIN_VALUE .

You may assign '\u0000' (or 0). For this purpose, use Character.MIN_VALUE.

Character ch = Character.MIN_VALUE;
