Hey guys.
Is there any possibility to provide casting for such a Java class in Kotlin: `public abstract class NumberExpression&lt;T extends Number &amp; Comparable&lt;?&gt;&gt; extends ...`
I've tried to do this `(expression as NumberExpression).goe(value)`, but this does not work.
I know, this is not a good practice, just to know... :slightly_smiling_face:

What type is `value` and whats the parameter type for `goe`?

Type of `value` and parameter type of `goe` is `T` from declaration of NumverExpression class.

Then there should not be the need for any cast? If you have `val value: T` then you can just pass it in.

Ou, I thought you mean the type in scope of NumberExpression.
Type of `value` is different from `T` in my class. That's why I need casting...

The problem here is that the `NumberExpression` class uses generics for `Number` and `Comparable&lt;*&gt;` at the same time.

This is the best I could come up with, using two unchecked casts.
You need a helper function so you can introduce an additional generic parameter.
