Summary of what is drilled

A Disciplined Approach? holds that these items should never again allow any confusion in your mind about this list of what Trevor covered in this lesson:

COVERED IN THE LESSON

• this needs to be covered by first by footguns and second by convention/examples
• example of constant - don't want to instantiate a class just to get the value
• example of instance based - should always instantiate a class to know that value
• naming convention for constant
• implied and left out - rarely if ever mix static and instance based anything - class is either static or instance based BY CONVENTION ONLY
• implied and left out - static methods are a bad code smell, even if technically possible
• implied and left out - what happens if static is treated as instance based are treated and setter changes the static variable in one instance and then another instance accesses it
• works but non-conventional because of power needed from better tech which is dependency injection
