NOTE: there is actually an error in one of the code examples, just to check if someone notices ;-)
Around 12'-13' the code "class Customer() {" should not have the "()".

Indeed some nice things to do with enums, and that customer state is indeed quite an apt example. And the code error was indeed spotted at the 12:04 mark. Thank you for the interesting video and blog post.

Wonderful video Frank. Learned a new thing in Java. Please also make videos on JavaFX tutorials. There are very few JavaFX tutorials online. Please keep posting videos regularly.

I came from reddit ! Nice content I want to be good programmer like you one day !! I have 5 years of exp and it feels like I know nothing

A few notes:
- your project directory has an .idea directory but you open it with vscode. You don't want to show people your IntelliJ? :)
- you're using java 17, aren't you? If yes, your switch (...) { case ...: return 1; ... } doesn't look very nice as there are a lot of return's in there.
- you use jband EnumExtended.java instead of java EnumExtendec.java. What's the advantage of using jbang over java?

I guess the only new thing I discovered here is JBang :)

Hey great overview of enum functionality, you could also show that an enum is basically a immutable class and can also implement interfaces, this could potentiality lead to interesting use cases like an light version of strategy pattern, also quick question, why you are doing Arrays.stream().sequential() is'n it sequential by default ? Other then this great video you got one more subscriber :D

I fail to see any benefit of enums over: final String[] values = { "X1", "X2", ..., "Xn" };

1. "Enum members are instances of the enum type" ehm, yeah. Surprise. It is the case since forever. It is not hidden, always been there. "Enum type much like any class can have fields and methods, including constructors". Yeah, nothing new really, nothing hidden either!
2. Also, cringe using java instead of normal javac->java sequence. You are targeting pupils, students, newbies! Don't teach them bad!
