Hey guys, junior here

Car

is a class, which extends an abstract class

Vehicle

I didn't write a constructor for

Vehicle

. why the compiler complains?

It just means you need to put

()

after

Vehicle

, which is a constructor invocation

But

Vehicle

is an abstract class. How is it possible that it has an implicit constructor? @Zach Klippenstein (he/him) [MOD]

There’s lots of information about this on the web. Kotlin takes its behavior from Java for this. Here’s some links: https://beginnersbook.com/2013/05/java-abstract-class-method/ https://stackoverflow.com/questions/260666/can-an-abstract-class-have-a-constructor https://www.geeksforgeeks.org/abstract-classes-in-java/
