Java, I cannot get my example class to run

I cannot compile and run my example.java class. When I terminate the repl and enter clear && javac Example.java && java Example I get his message...

Example.java:6: error: constructor PezDispenser in class PezDispenser cannot be applied to given types;
PezDispenser dispenser = new PezDispenser();
^

reason: actual and formal argument lists differ in length
Example.java:12: error: cannot find symbol

./PezDispenser.java:19: error: missing method body, or declare abstract

5 errors

Here is my code...

public class Example {

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

}
