Both A T and Faber's solutions should work fine if you add the check for uppercase letters also:
String foo = "aAsdjshdIUjkshf"; System.out.println(foo.matches("[a-zA-Z]+") ? "Yay" : "Nay" ); Prints 'yay'. String foo = "aAsdjs1234hdIUjkshf"; System.out.println(foo.matches("[a-zA-Z]+") ? "Yay" : "Nay" ); Prints 'nay'.
