pezAmount in catch part of the code

Hey there,

unreal tutorial. I tried one additional thing - to say how much PEZes is too much (actually it is not a big use of it because user knows what he typed in, but still). So I need to show a message like "%s is too much PEZ" in catch part, so here what I tried:

try {
  dispenser.fill(50);
  System.out.printf( "%s PEZ overall", dispenser.getPezCount() );
} catch ( IllegalArgumentException iae ) {
  System.out.printf("%s is too many PEZ %n", dispenser.pezAmount );
}

but it throws that it can't find pezAmount variable. Probably because of the scope?

So I tried get the pezAmount in the IllegalArgumentException message and then get that message to show in the catch part but it shows

./PezDispenser.java:18: error: incompatible types: int cannot be converted to Throwable
throw new IllegalArgumentException("%d is too many PEZ", pezAmount);

What do You recommend? What is the way? Thanks!
