Need help here.

Question

How do you remove the duplicate result showing from the output?? here is my code :

System.out.println("Enter letters only");
String alpha = scan.nextLine();
String numb = "[0-9]";

if(alpha.matches("[a-zA-Z]")) {
System.out.println(alpha);
}else
System.out.println(alpha.replaceAll(numb , " not a letter"));
}
}

INPUT

OUTPUT

I want it to be ( qwerty not a letter ).
