Lecture Outline

• Static method (a method that you can call without needed to create an object of that class)
• Try/Catch allows us to deal with errors without crashing the program
• Abstract classes are a superclass (A class that is inherited from) that cannot be instantiated and is used to state or define general characteristics. Ie. you CANNOT create an instance of an abstract class
• The debugger is an incredibly powerful tool in your IDE. You must first place a breakpoint somewhere in your code (double click a line number) and then select the debug option
• Rubber duck debugging can be a helpful solution to identify and fix bugs in your code
