you can use a regex
[^A-Za-z] will match non-alphabetical characters
you can replace all of them using .replaceAll
if you are allowed to use regexes
if not, ho over all characters, check if it's alphabetical and remove them if they aren't

note: don't loop over the same string you're removing from, that causes issues
best way is to create a new string/stringbuilder from the chars that are alphabetical for a simple approach, or you could use streams and filter if you can use streams
