Trying to implement strategy pattern. Let me know if this is bad code

What error? Works fine for me https://pl.kotl.in/gZPnK0byh Just write

object

instead of

Object

.

Also, is this correct?

val labelByCategoryMap = mapOf(
            ShippingLabelCategoryConstants.FRESH to FreshLabelPrinter,
            ShippingLabelCategoryConstants.PHARMA to PharmaLabelPrinter
    )

where

FreshLabelPrinter, PharmaLabelPrinter

are objects

Sure

yeah they do. Let me share the exact scrensot

FreshLabelPrinter

does not implement any interface, so I can guess that your map

labelByCategoryMap

will have type

Map<ShippingLabelCategoryConstants, Any>

, that’s why method is not available.

Please suggest me a better alternative implementation

If I understood your use-case correctly, then this may help https://pl.kotl.in/HMdOjuGHP

Thank you so much! It looks the interface is missing. 🙂
