Hi, I want to three strings in an input = {"corn,mix veg,cheese"} using a consumer interface and then print them using supplier interfcae. Also, I need to check that if even one of the strings is other than these three values i.e. corn, mix veg or cheese (in any order) , then it should display "Incorrect Input". Can you please help me how to do it using these functional interfaces ?
