57,712 PointsHiya,
The variable iae holds an instance of Illegal Argument Exception. That class has an instance method called getMessage() that retrieves the message associated with the error that generated the instance. In this case, you created an instance with:
throw new IllegalArgumentException("Too many PEZ!!");
So, this line gets called as you throw the error, the instance it creates gets stored in iae and you use the getMessage()` method on that instance to retrieve the message passed in with the constructor, "Too many PEZ!!!".
I hope that helps.
Steve.

Short answer; no.
A class can have no constructor (Java will provide a default one) or any number of constructors, as long as each one has a different signature. If each constructor requires different parameters there can be multiple constructors present.
