Okay, so i have a doubt about that Random

When he says lucky.nextBoolean() he is randomly alterning in between true and false because thats a method of the Random class? and if yes wouldn't he need to import a library like he did when when we were using de IO library?

There's a "blink and you'll miss it" spot at 1:15 where he's at the top of the code before he scrolls down. You'll see an import java.util.Random; there already.

Yes he is randoming the boolean variable lucky. As Seth Kroger state it you can see at 1:15 random library is included. You can also check his final code under teachers note -> workspace snapshots -> ending point -> MiniGolf.java.
