You can use the replaceAll()function.
您可以使用该replaceAll()功能。
For your case:
对于您的情况：
replaceAll("\s","")
where \smeans any whitespace (such as a space character).
where\s表示任何空格（例如空格字符）。
回答by Dhanendra Pratap Singh
You just need this function. replaceAll()
你只需要这个功能。 replaceAll()
str.replaceAll("\s","")
\s= Anything that is a space character (including space, tab characters etc)
\s= 任何空格字符（包括空格、制表符等）
You need to escape the backslash if you want \s to reach the regex engine, resulting in \s. Like wise we use :-
如果您希望 \s 到达正则表达式引擎，则需要转义反斜杠，从而导致 \s。像我们一样明智地使用：-
\S= Anything that isn't a space character (including both letters and numbers, as well as punctuation etc)
\S= 任何非空格字符（包括字母和数字，以及标点符号等）
\w= Anything that is a word character
\w= 任何是单词字符的东西
\W= Anything that isn't a word character (including punctuation etc)
\W= 任何非单词字符（包括标点符号等）
