error: could not find or load the main class example

I have two files open, that is what my instructor told me to do. For some reason, my console cannot find or load the main class example.

File one ( Example.java ) reads:

public class Example {

public static void main(String[] args) {
    // Your amazing code goes here...
    System.out.println("We are making a new pez");
    PezDispenser dispenser = new PezDispenser ("Yoda");
    System.out.printf("The dispenser chracter is %s",
                      dispenser.getCharacterName());
  if (dispenser.isEmpty()) {
  System.out.println("It's empty");
  }
  System.out.println("Loading...");
  dispenser.load();
  if (!dispenser.isEmpty()) {
    System.out.println("It's no longer empty!");
    }
}

}

File two ( PezDispenser.java ) reads:

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; }

}
