I need to null check nested method calls like so:
if (getShopModel() != null && getShopModel().getType() != null)
I don’t think this is the best way to do it though as I am calling getShopModel twice which could be quite expensive.
Is there a better way to check getShopModel().getType() in such a way that I only need to call getShopModel() once?
Use a variable…
This costs you nothing, saves an extra call, and might even make it easier to debug should you be interested of the value returned by ‘getShopModel’.
