String str = "she sells sea shells";
String rex = "\\Ss\\S";

Explanation:

Therefore, \\Ss\\S matches any s that is surrounded by a non white space character on both sides.

Why doesn't it found the first and last 's' on this string ? So they are not surrounded by space

\\S means non-white space. Word boundary is not considered as non-white space.

Do you mean word-boundary is considered a white space ?

No, this particular word boundary is just a word boundary

Neither whitespace nor non whitespace.
All white spaces are considered word boundaries but not the reverse.
