This is the 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;
    mPazCount = 0;
  }

  public boolean isEmpty(){

    return mPezCount == 0;
  }

  public void load(){
    mPezCount = MAX_PEZ;
  }


  public String getCharacterName(){
    return mCharacterName;
  }
}

When i load it in repl it shows me this :

java> :load PezDispenser.java
Loaded source file from PezDispenser.java
java> PezDispenser pd = new PezDispenser("Yoda");
java.util.NoSuchElementException

Does anyone know what it is or where i make the mistake?

Thank you very much!

Whoops!

mPazCount = 0;

Protip: If you call javac on the file, I think it will probably point to that error.

Hey Craig,

Cant believe that is really you! Awesome class!! Your clear and very funny :) Thank you for your replay,i resolve the bug with the mPazCount = 0; ,i save it and again it show me the same error:

I run javac and it says : Error: Main method not found in class PezDispenser, please define the main method as:
public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application
^

You sure you ran javac and not java on the file? That error sounds very much like when you run the command java on a class that does not have a main method (which PezDispenser doesn't have).

You have totally right! I was running javac in PezDispenser : clear && javac PezDispenser.java && java PezDispenser. (My bad!)

I just run javac Example and is working! Then i load :

java> :load PezDispenser.java
Loaded source file from PezDispenser.java
java> PezDispenser pd = new PezDispenser("Yoda");
PezDispenser pd = PezDispenser@4800587f

And Yay!! is working.Thank you very much !!
