Java Java Objects (Retired) Harnessing the Power of Objects Exceptions

my code doesn't show the same result

this is my code

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

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

  public void load() {

  load(MAX_PEZ);

  }

  public void load(int pezAmount){

    mPezCount += pezAmount;
  }

  public void load(int PezAmount){

    int newAmount = mPezCount + pezAmount;
    if (newAmount > MAX_PEZ) {
      throw new illegalArgumantExeption("Too many PEZ!!");
    }
    mPezCount = newAmount;
  }

  public String getCharacterName(){
    return mCharacterName;

     }
}
public class Example {

        // Your amazing code goes here...
        System.out.println("We are making a new Pez Dispenser.");

//Delete this load method. Because of the load method you have below, you no longer need this.
  public void load(int pezAmount){

    mPezCount += pezAmount;
  }

  public void load(int PezAmount){
                     //^First p should be lowercase.
    int newAmount = mPezCount + pezAmount;
    if (newAmount > MAX_PEZ) {
      throw new illegalArgumantExeption("Too many PEZ!!");
              //^Should be spelled "illegalArgumentException"
    }
    mPezCount = newAmount;
  }

this is my PezDispenser.java now

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

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

public void load() {

load(MAX_PEZ);

}

public void load(int pezAmount){

mPezCount += pezAmount;

}

public void load(int PezAmount){ //^First p should be lowercase. int newAmount = mPezCount + pezAmount; if (newAmount > MAX_PEZ) { throw new illegalArgumantExeption("Too many PEZ!!"); //^Should be spelled "illegalArgumentException" } mPezCount = newAmount; }

public String getCharacterName(){ return mCharacterName;

 }

}

and it shows me this error ./PezDispenser.java:34: error: method load(int) is already defined in class PezDispenser
public void load(int PezAmount){

You are not throwing the right exception. Try this: throw new IllegalArgumentException("Too many PEZ!!!")
