error: cannot find synbol if (dispense.isEmpty()) { ^

I get this error when trying to run example at the end of the video.

Example.java:27: error: cannot find symbol
if (dispense.isEmpty()) {
^
symbol: variable dispense
location: class Example
1 error

here is what i wrote in PezDispenser.Java

public boolean dispense() { boolean wasDispensed = false; if (!isEmpty()) { mPezCount--; wasDispensed = true; } return wasDispensed; }

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

public void load() { //public method that returns nothing( void ) load(MAX_PEZ); // turns mPezCount into the MAX_PEZ count } // used to be mPezCount = MAZ_PEZ;

public void load(int pezAmount) { mPezCount += pezAmount; }

here is the code in Example.java

System.out.println("We are making a new Pez Dispenser.");
  PezDispenser dispenser = new PezDispenser("Yoda");
  System.out.printf("The dispenser character is %s\n", 
                   dispenser.getCharacterName());

  if (dispenser.isEmpty()) {
    System.out.println("It is currently empty");
  }
  System.out.println("Loading...");
  dispenser.load();
  if (dispenser.isEmpty()) {
    System.out.println("It is no longer empty");
  }
  while (dispenser.dispense()) {
    System.out.println("Chomp!");
  } 
  if (dispense.isEmpty()) {
    System.out.println("Ate all the PEZ!");
  }
  dispenser.load(4);
  dispenser.load(2);
   while (dispenser.dispense()) {
    System.out.println("Chomp!");
   }
}

}

Hello,

I think you wanted to call that as:

if (dispenser.isEmpty()) {
    System.out.println("Ate all the PEZ!");
  }

since your PezDispenser is named dispenser.

Wow, thank you so much. I can't believe I over looked that misspelling so many times. The code works as expected now.
