How can Java class extend Kotlin library?

I understand what all kotlin classes are final.

I have library and I need to override some methods. But then I extend library, I'm getting error

public class Editor extends EditorLibrary //error Cannot inherit from final

Any chances to extend kotlin final class, because I can't change it to open?

CodePudding user response：

If you have control over the library you can open the class for extension using the open keyword, otherwise, as you've mentioned, the class was not built for extensions...

open EditorLibrary(...) {
}

In such case you might consider using composition over inheritance... e.g. :

public class Editor {
    private final EditorLibrary editor;
    
    ...
}
