Regex doesn't work in String.matches()

Question

I have this small piece of code

String[] words = {\"{apf\",\"hum_\",\"dkoe\",\"12f\"};
for(String s:words)
{
    if(s.matches(\"[a-z]\"))
    {
        Syste         


        

Answer 1

String.matches returns whether the whole string matches the regex, not just any substring.
