I am trying to match "tab" and "newline" meta chars but without "spaces" with REGEX in Java.
我试图匹配“tab”和“newline”元字符，但没有“空格”与Java中的REGEX。
\s matches evrything i.e. tab, space and new line... But, I don't want "space" to be matched.
\ s匹配evrything，即tab，space和new line ......但是，我不希望“space”匹配。
How do I do that?
我怎么做？
Thanks.

One way to do it is:
一种方法是：
[^\\S ]
The negated character class makes this regex to match anything except - \\S (non-whitespace) and " "(space) character. So, it will match \\s except space.
否定的字符类使此正则表达式匹配除 - \\ S（非空格）和“”（空格）字符之外的任何内容。因此，除了空格之外，它将匹配\\ s。

Explicitly list them inside [...] (set of characters):
在[...]（字符集）中明确列出它们：
"[\\t\\n\\r\\f\\v]"
