ERROR: not a statement; ERROR: cannot find symbol

Why this happen when I load PezDispenser.java on repl?

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 void load(){
    mPezCount = MAX_PEZ;
   }
   public boolean isEmpty(){ boolean isActuallyEmpty = mPezCount == 0; return isActuallyEmpty; }

   //Creates a public class that gets the private object above. 


  // This was commented out
   public String getCharacterName() {
      return mCharacterName; 
   }

 }

Can you post your code from PezDispenser.java?

I'm not sure if you got this working but I was getting the exact same error when I tried to pass "PezDispenser.Max_Pez" instead of "PezDispenser.MAX_PEZ" which may mean you have a typo somewhere (I couldn't find it in your code though).

Hope this helps someone else who's getting this error.

I have the exact same error:

treehouse:~/workspace$ javac Example.java ./PezDispenser.java:12: error: cannot find symbol return isActuallyEmpty = mPezCount == 0; ^ symbol: variable isActuallyEmpty location: class PezDispenser 1 error

My PezDispenser.java looks like this: 

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 isActuallyEmpty = mPezCount == 0; 
  }

 public void load() {
  mPezCount = MAX_PEZ; 
 }


 public String getCharacterName() {
  return mCharacterName; 
 }
}

Looks like that line where you declare isActuallyEmpty is missing. Not sure exactly where you are at, but if you remove that and make the line:

return mPezCount == 0;

It will be much happier.

Hope that helps.
