Creating Classes

Kotlin differs quite a bit from Java in how classes are defined. Writing classes in Java involves so much boilerplate code. To alleviate the pain of typing all that, programmers rely a lot on IDEs to generate code. Good news, you don’t need to type as much. Bad news, you’ll have to wade through all that code each day.
