I can't compile java file. And when I tried to declare a object, they said Java.util.NoSuchElementException

This is code for my Exemple.java

public class Example {

public static void main(String[] args) {
    // Your amazing code goes here...
System.out.println(" we're making a new PezDispenser.");
// PezDispenser dispencer = new PezDispenser("Donatello");
// System.out.printf("The dispenser charater is %s",dispencer.getCharacterName());

}

}

I tried to find error by excluding it with //, however with bad luck they still showed me a error message "Error: Could not find or load main class Example.java"

This is class file. I don't sure what is the problem. If anyone can enlighten me. I'll really appreciate.

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 mPezCount ==0; }

public void load() { mPezCount = MAX_PEX; }

public String getCharacterName(){ return mCharacterName; } }

You have a mis-spelling.

public class PezDispenser {
    public static final int MAX_PEZ = 12;    //MAX_PEZ
    . . .

public void load() { 
    mPezCount = MAX_PEX;                    //MAX_PEX
}

Yes, I tried that out already but I still can't compile the main file (Example.java) They always said "Error: Could not find or load main class Example.java".

This is the Example class. It must be in a file named Example.java:

public class Example {

   public static void main(String[] args) {

      // Your amazing code goes here...
      System.out.println(" we're making a new PezDispenser.");
      PezDispenser dispencer = new PezDispenser("Donatello");
      System.out.printf("The dispenser charater is %s", dispencer.getCharacterName());
   }
}

This is your PezDispenser class. It must be in a file named 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 mPezCount ==0;
   }

   public void load() {
    mPezCount = MAX_PEZ;
   }

   public String getCharacterName(){
    return mCharacterName;
   }
}

I've loaded both files into my Java IDE and they run fine. I suggest you delete yours, and create new files with the above, just to shortcut trying to find the differences. Good luck.
