import java.util.Scanner;

public class NameSong {
   public static void main (String [] args) {
      String secondVerse = "Banana-fana fo-f(Name)!";
      String userName = "Katie";

      userName = userName.substring(1); 
{
    secondVerse = "Banana-fana fo-f"+userName+"!";
}
      System.out.println(secondVerse);

      return;
   }
}

Why do I get this output?

 Testing Katie

 Testing Walter

✖
 Testing Katie and ending with !!! instead of !

Thank you...
