Regex matching whitespace and well as non-white space

Question

I am trying to match a string.

1. String can contain whitespaces

2. The string should contain atleast one non-white space character.

I tried,

[^\s]

This is matching all non-white space characters.

Any improvement to the above regex will be helpful

Answer 1

如果问题可以简化为“任何问题，只要有一个非空白字符，那么.*\\S.*应该起作用。

Answer 2

尝试.*\\S.*这应该与您所追求的相符

Answer 3

\\S is equivalent to [^\\s] . Was that your question?

Answer 4

Update, misread the question.

Try .*\\w.* as your expression. This will match any string that contains at least a single non-white space. In defining your regex, make sure to escape the backslash, so use ".*\\\\w.*" as your String.
