Noun. 1. alphabetic character - the conventional characters of the alphabet used to represent speech; "his grandmother taught him his letters" letter of the alphabet, letter. spelling - forming words with letters according to the principles underlying accepted usage.
You can use the regular expression 'r[^a-zA-Z]' to match with non-alphabet characters in the string and replace them with an empty string using the re. sub() function. The resulting string will contain only letters.
[A-Za-z] will match all the alphabets (both lowercase and uppercase). ^ and $ will make sure that nothing but these alphabets will be matched.
The method string. isalpha() checks whether string consists of alphabetic characters only. You can use it to check if any modification is needed.
You can use String.replaceAll(regex, replacement) with the regex [^A-Za-z]+ like this:
String newstr = "Word#$#$% Word 1234".replaceAll("[^A-Za-z]+", ""); // newstr will become WordWord Edit: Although OP hasn't mentioned anything about unicode characters but since @Joey has made a comment and if at all there a requirement to keep unicode characters then \\P{L}+ regex should be used like this:
String newstr = "Word#$#$% Word λ1234ä, ñ, ж".replaceAll("\\P{L}+", ""); // newstr will become WordWordλäñж If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
