Java Regex that only replaces multiple whitepaces with Non-Breaking Spaces

Question

I am looking for a Java regex way of replacing multiple spaces with non-breaking spaces. Two or more whitespaces should be replaced with the same number of non-breaking spa

Answer 1

You could also skip the regex all together.

String testStr = "TESTING THIS  OUT   WITH    DIFFERENT     CASES";
String _replaced = testStr.replace("  ", "  ");
String replaced = _replaced.replace("  ", "  ");

I haven't tested this but the first one finds all cases of two spaces and replaces them with non-breaking spaces. The second finds cases where there were an odd number of white-spaces and corrects it with two nbsps.
