How to remove ordinal value in Java?

Question

I have Station Names like 23 St, 21 St in our mysql database.

I am applying Lucene Algorithm to search the stations in Java.

For 23 St user can give inputs like 23rd St, 23rd etc.

I want to remove Ordinals from the given inputs, like if user gives 23rd St then I want it to replace with 23 St.

So is there any way to remove ordinal value in Java?

Answer 1

This will remove ordinals:

String s = s.replaceAll("(?<=\\d)(rd|st|nd|th)\\b", "");
