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'.
