Regex doesn't work in String.matches()

I have this small piece of code

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

You can make your pattern case insensitive by doing:

Pattern p = Pattern.compile("[a-z]+", Pattern.CASE_INSENSITIVE);
