Java Java Annotations Using Java's Built-In Annotations The @SuppressWarnings Annotation - Suppressing Multiple Warnings

Java Annotations (I need help on this question)

In the console.txt file, you see some sample output as a result of compiling the Stuff class. After looking at the compiler output, add the correct @SuppressWarnings annotation that suppresses the warnings listed. Keep in mind that these warnings are fictitious, and that there is intentionally no code in the doThings method. The only thing you need to add is the correct annotation.

public class Stuff {
  public void doThings() {
    // Nothing to see here

    // Or here

    // Or here

    // Or here

Stuff.java:6 warning: [spellingerror] A spelling error was found. Wherever possible,
  use correct spelling.
Stuff.java:9 warning: [asleeponkeyboard] You have a sequence of characters suggesting 
  that you fell asleep on your keyboard.
Stuff.java:12 warning: [wet] Duplicate code above this line suggests that you may be 
  violating the DRY principle. Remember: Do not Repeat Yourself.

If you completed the previous challenge, you should at least be able to add the annotation to the code.

Then you might want to review the last video lesson, where an example was shown of how to use the suppresswarnings annotation with multiple warning types.
