java.util.NoSuchElementException?

Here is my code in PezDispenser.java :

public class PezDispenser {
  public static final int MAX_PEZ = 12;
  private String mCharacterName;
  private int mPezCount;
  public  PezDispenser(String characterName) {
   mCharacterName = characterName; 
   mPezCount = 0;
  }

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

  }

  public void load() {
    mPezCount = MAX_PEZ; 
  }

  public String getCharacterName() {
   return mCharacterName; 
  }
}

The problem is that whenever I type PezDispenser pd = new PezDispenser("Yoda"); in the java-repl, it says, java.util.NoSuchElementException.

Please help. Thanks!

For anyone else looking for an answer on this message. The previous answer said there was a missing class. I went back to the previous videos and followed along. I finally decided to press on and found that it was a typo in my code that was causing the message. I was tipped off by googling the error message. It led me to a stack overflow article that mentioned a semicolon in the class. Sure enough, I had put a semicolon at the end of the isEmtpy method.

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

I typed isEmpty();

After I removed the semicolon and saved I was able to go back and finish the exercises in this video.
