Error java.util.NoSuchElementException

I have been looking for a misspelling or something missing from the code, but can't seem to see anything.

My Code:

public class PezDispenser {
  public static final int MAX_PEZ = 12;
  private String mCharacterName;
  private int mPezCount;

  public PezDispenser(String characterName) {
    mCharacterName = characterName;
  }

  public String getCharacterName() {
    return mCharacterName;
    mPezCount = 0;
  }

  public boolean isEmpty() {
    return mPezCount == 0;    
  }


  public void load() {
    mPezCount = MAX_PEZ;
  }
}

The Console Error:

I've only ever seen this Exception on team treehouse, so maybe it's the way they compile things. But it looks like since you didn't initialize your variable "mPezCount" it just can't run properly. Giving you a runtime error.

From what I see, you put your "mPezCount = 0;" in your "getCharacterName()" method. It would also never be run since it was placed after a return statement.

Answer: Basically all you need to do is cut that line from the "getCharacterName()" method, then paste it to your constructor method (the public PezDispenser(String characterName) method).

This same thing happened to me, but my code was already arranged like you told Howard. Hmmm...

public class PezDispenser { public static final int MAX_PEZ = 12; private String mcharacterName; private int mPezCount;

public PezDispenser(String charName) { mcharacterName = charName; mPezCount = 0;

}

public boolean isEmpty() { return mPezCount == 0;

}

public void load() { mPezCount = MAX_COUNT; }

public String getName() { return mcharacterName; } } I got the same error.

Thomas,

First, and this is just for naming conventions' sake, I noticed you didn't correctly camel case your "mcharacterName" variable. This won't cause any problems unless you are inconsistant with it, but it looks like you stuck with that naming for all instances. For better readabillity, it should be "mCharacterName". Just a good practice to keep.

Second, I noticed you initailized "MAX_PEX" at the top then tried to recall it as "MAX_COUNT" in the load() method.

It should work after that is corrected.

Also, since I can't see your Example.java file, I'm not sure if you had an issue with calling the methods between the two files or not. For example, you used "getName() in your last method. Make sure in the Example file you used the same method name instead of something like "getCharacterName()" or "getCharName()" or it won't know what you're referring to.
