Try replaceAll with a regular expression that matches a comma and the surrounding whitespaces and replaces it with just the comma:

s = s.replaceAll("\\s*,\\s*", ",");

See it working online: ideone

Note: This won't remove spaces at the beginning or end of the line. To remove those too you could modify the regular expression, but simpler is to just call String.Trim afterwards.

You can either replace (commas surrounded by whitespace) with just commas, or Split on commas, then join the trimmed results.
