See how to use this form of Regex below to identify whether or not a string has only alphabets present.

public class RegexHasOnlyAlphabets{      public static void main(String args[]) {      RegexHasOnlyAlphabets regexHasOnlyAlphabets = new RegexHasOnlyAlphabets();      regexHasOnlyAlphabets.proceed();   }   public void proceed()    {      String inputStr = "HasOnlyAplhabets";      System.out.println("Has only alphabets: " + inputStr + ": " + checkIfInputHasOnlyAlphabets(inputStr));      inputStr = "HasOnly3Aplhabets";      System.out.println("Has only alphabets: " + inputStr + ": " + checkIfInputHasOnlyAlphabets(inputStr));   }            public boolean checkIfInputHasOnlyAlphabets(String strArg)    {      return          (            (null != strArg) &&          (! strArg.equals("")) &&         (strArg.matches("^[a-zA-Z]*$"))         );    }       }/*

Expected output:
