I cannot get Yum Yum Yum to print , please HELP :(

I cannot get Yum Yum Yum to print , I have looked over my class and still cant find whats different between mine and craigs--here are the screen shots --https://w.trhou.se/mfz9bpd4kn

public class Example {

  public static void main(String[] args) {

    PezDespenser despenser = new PezDespenser("vegeta");

    //String differentCharacter = despenser.swapCharacters("Freeza");

    while(despenser.dispense()){
      System.out.println("yum");
    }
    if(despenser.isEmpty()){
      System.out.println("all gone");
    }

  }

}

class PezDespenser{

  public static final int MAX_PEZ = 12;
  final private String character;
  private int pezCount ;

  // when declaring a constructor you want to name it the same as your CLASS !!!

  public PezDespenser(String character){
    this.character=character;
  }

  public String getCharacter(){
    return character;
  }

  public void fill(){
    pezCount = MAX_PEZ;
  }
  public boolean isEmpty(){
    return pezCount == 0;
  }
    public boolean dispense(){
    boolean isDispensed = false;
    if(!isEmpty()){
       pezCount--;
      isDispensed = true;
    }
      return isDispensed;


}
}

Hi there! First, when I look at Craig's code he has many more lines in Example than what you have. That being said, I took a look at your workspace and the reason your code is never printing "yum", is because you never fill the PezDispenser with pez. There is nothing to munch :smile:

If I alter your code just slightly by adding one line, it starts printing "yum":

PezDespenser despenser = new PezDespenser("vegeta");
despenser.fill();

The first line, you have already in Example.java. I simply added the second line which puts pez in the dispenser.

Hope this helps! :sparkles:

Omgoodnesss !! thank you soooo much , i cannot believe i did not see that. I LOVE TREEHOUSE !!

I think you need to overload the method fill by which you can prompt the user for pezCount. then you need to call the dispenze mehod.
