    11. Exception Handling: Risky Behavior
    Let’s make a Music Machine
    We’ll start with the basics
    First we need a Sequencer
    The compiler needs to know that YOU know you’re calling a risky method
    An exception is an object... of type Exception
    If it’s your code that catches the exception, then whose code throws it?
    Flow control in try/catch blocks
    Finally: for the things you want to do no matter what
    Did we mention that a method can throw more than one exception?
    Exceptions are polymorphic
    Multiple catch blocks must be ordered from smallest to biggest
    You can’t put bigger baskets above smaller baskets
    When you don’t want to handle an exception...
    Ducking (by declaring) only delays the inevitable
