Java - Regex - Replace multiple dots and commas with just one dot

Using TextField to place double/integer numbers, want to change any number with "," to number with "." and remove multiple dots and commas.

String test = "0....,,,,,,,....754568";
test.replaceAll(<?IDK?>, ".");

<?IDK?> means that I don't know what to put there.

Examples:
4,5 → 4.5
6,,,,2 → 6.2
0....,,,,,,,....754568 → 0.754568
7...2 → 7.2

You can have a regular expression, for example, to identify numbers which have more than one dot or comma you can use the following : 

\d+[.,]{2,}+\d

You can adjust it based on your needs.
