PezDispenser dispenser = new PezDispenser("Yoda");

Why would this error come up:

java.util.NoSuchElementException

I did not change the code from the previous section but I could not do the Methods and Commands workspace activity. :(

java.util.NoSuchElementException is a RuntimeException which can be thrown by different classes in Java like Iterator, Enumerator, Scanner or StringTokenizer. All of those classes has method to fetch next element or next tokens if underlying data-structure doesn't have any element Java throws "java.util.NoSuchElementException".

Anyway if you would like to show us your code, maybe we can help you.

Hi Kamran,

I believe that there's some error in your second line of code: public static final int String mCharacterName;

  • a variable cannot have two datatypes (int String) -the (public static final) portion is telling the compiler that the variable value will not change, but in this case, mCharacterName can change with each object.

Perhaps the code should be:

public static final int MAX_PEZ = 12;

String mCharacterName;

I hope that this helps :)
