Lecture Outline

• A reference value is a pointer to an object in memory
• References can share an object
• If you update an object, it will update it for all other references that share it.
• When comparing strings, you should still always use .equals()
• 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
