How to make regex accept only uppercase and lowercase letters with accents in java? [closed]

Answer 1

In my opinion You get true, because regex is focused on finding letters. It would say false only, when You test string with no letters at all. Please consider changing if else statement and regex to find out if there are other symbols than letters:

Pattern pattern = Pattern.compile("[^\w]");

Matcher matcher = pattern.matcher("testTest");

if (matcher.find()){
    tv.setText("false");
}
else{
    tv.setText("true");
}

Hope it helps. Cheers.
