Here is my code
class Example {
public static void main(String[] args) {
System.out.println("we are makeing a a new pez disenser");
PezDispenser dispenser = new PezDispenser("Yoda");
System.out.printf("Fun fact a pez dispenser can only hold %d pez %n",
dispenser.MAX_PEZ);
System.out.printf("The Dispenser is %s %n",
dispenser.getCharecterName());
if(dispenser.isEmpty()) {
System.out.println("Your Dispenser is empty");
System.out.println("________________________________");
System.out.println("Filling your PezDispenser ... ");
dispenser.fill();
}
if(dispenser.getPezCount() == dispenser.MAX_PEZ) {
System.out.println("________________________________");
System.out.println("Your Pez Dispenser is full");
System.out.println("________________________________");
} else {
System.out.println("________________________________");
System.out.printf("You have %d pez %n",
dispenser.getPezCount());
System.out.println("________________________________");
}
while(dispenser.getPezCount() > 0){
System.out.println("CHOMP! ...");
dispenser.eatOne();
}
if(dispenser.isEmpty()){
System.out.println("You ate all the pez");
}
dispenser.fill(2);
dispenser.fill(6);
System.out.println("Added 8 pez");
while(dispenser.getPezCount() > 0){
System.out.println("CHOMP! ...");
dispenser.eatOne();
}
try {
dispenser.fill(100);
System.out.println("Adding 100 Pez");
} catch(IllegalArgumentException iae) {
System.out.printf("Error %nError : %s %n",iae.getMessage());
}
}
}

Error : Too many Pez
if you need it here is my PezDispenser.java
class PezDispenser {
public static final int MAX_PEZ = 12;
private String charecterName;
private int pezCount;
public PezDispenser(String charecterName) {
this.charecterName = charecterName;
}
public boolean isEmpty() {
return pezCount == 0;
} //isEmpty()
public void fill() {
fill(MAX_PEZ);
} //fill()
public void fill(int pezAmount) {
int newAmount = pezCount + pezAmount;
if(newAmount > MAX_PEZ) {
throw new IllegalArgumentException("Too many Pez");
}
newAmount = pezCount;
}
public void addOne() {
pezCount ++;
} //addOne()
public void eatOne() {
pezCount--;
} //eatOne()
public String getCharecterName() {
return charecterName;
} //getCharecterName()
public int getPezCount() {
return pezCount;
} //getPezCount()
}

28,558 PointsThe fill(int pezAmount) method does not actually fill the PezDispenser because the last line:
newAmount = pezCount;
Is the opposite of what it should be, you are meant to set the pezCount equal to the newAmount like this:
pezCount = newAmount;
Otherwise you will always end up with 0 pez in the dispenser.
Fixing that error should make your code act as intended.
