daria :
I am trying to replace all characters that are not letters in a string, but keep the spaces between words.
The code I have so far:
String newWords = words.replaceAll("[^A-Za-z0-9 ]", "");
I also tried this one:
[^a-zA-Z0-9\\s]
The problem with the code is that it removes everything but the numbers in the string.
Pshemo :
It deletes the dot between the 87.97, but wont remove the numbers itself
[^...] means every character except. So [^A-Za-z0-9 ] means: match (and replace/remove) everything except A-Z a-z 0-9 and space. In other words those characters are protected from removal.
If you also want to remove numbers (series of digits) remove 0-9 from your regex.
String newWords = words.replaceAll("[^A-Za-z ]", "");
