Printer challenge tests broken?

So in the functional programming coding challenge I also get an error that 1 of the 3 tests failed.

16:02:09: Executing task 'prepareSubmission'...

But I think my code is correct. I just can't figure it out...

package com.teamtreehouse.challenges;

import java.util.Arrays;
import java.util.List;
import java.util.function.Consumer;

public class Printer {

  public static void main(String[] args) {
    List<String> chipmunks = Arrays.asList("Alvin",
      "Simon",
      "Theodore");
    System.out.println("Imperative results:");
    printChipmunksImperatively(chipmunks);
    System.out.println("Declarative results:");
    printChipmunksDeclaratively(chipmunks);
  }

  public static void printChipmunksImperatively(List<String> chipmunks) {
    for (String chipmunk : chipmunks) {
      System.out.printf("%s! %n", chipmunk);
    }
  }

  public static void printChipmunksDeclaratively(List<String> chipmunks) {
    // TODO: Print out each of the chipmunks using the forEach method on Iterable
    chipmunks.forEach(chipmunk -> System.out.println(chipmunk));
  }


}

It seems to be missing that exclamation mark. Functionally it looks good ;)

it would be nice if you can write better in PrinterTestclass to throw an exception " you are almost there, missing exclamation mark" .. lol.
