A modern programming language that makes developers happier.

kotlinlang

Hi, I'm following the Udacity bootcamp and one of the examples in the lecture doesn't work for me, this is the code:

```package aquarium

class Aquarium (var length: Int, var width: Int, var height: Int) {

    var volume: Int
        get() = width * height * length / 1000
        set(value) = {height = (value * 1000) / (width * length)}```

This is the warning I'm getting from Intellij for the set(value):

```Type mismatch: inferred type is () -> Unit but Unit was expected```
I don't understand what is this supposed to signify?

You need to remove the `=` after `set(value)`

You need to remove the the `=` in `set(value) = { ... }` otherwise you are indicating that the setter is returning a lambda. The `Type mismatch: inferred type is () -&gt; Unit but Unit was expected` is indicating that by stating that the compiler is expecting a `Unit` type but is finding `() -&gt; Unit` as type. Remember that a `{` starts a block and that `}` ends a block, and assigning a block is creating a lambda. I make that mistake a lot too, even after working with kotlin for years. :sweat_smile:
