This was very concise and well explained. I learned OOP and did a lot of projects/homeworks earlier this year in a class and I always tell people "any concept, specifically in CS, is simplifiable", but school doesn't do an amazing job at concise. I had a wonderful professor for OOP but in general teachers make things more complex and drag on lessons. 2 things that would have perfected this video: 1 if you had prepared a full class with variables and functions, like a full 40 line class with edge case checking for constructors and setters. 2 split the screen between "class containing main method where objects r created" and "actual class/blueprint of object" that way people can visualize things much better. for a quick intro to OOP, this was very good. even for a review for test.

Great video! Just want to add that getter and setter methods make getting and setting variables easier for users, because the original developer(you) is(are) able to retrieve and replace the variable in different ways depending on what the user submits as a parameter to each method. Mainly, if the original dev(you) wants(want) to make sure users don't accidentally set a variable to certain values down the line, getters and setter methods can perform checks and do much more than simply *get* and *set* the variable in question when the user calls them
