How would you sum up interface testing?
Create a test project to play with the Comparable interface. Edit the Card class to implement Comparable . Cards are to be compared using their value. They are considered the same if they have the value. One is less than the other if its value is less. Add the compareTo method that takes a Card object as a argument and returns 0 meaning the values are the same, 1 meaning the card is greater than the parameter, -1 meaning the card is less than the parameter. Create a main() that creates a Deck. Use your code from the program that dealt out Cards from a Deck and showed the hands but this time, now that Cards are comparible, show them in sorted order using Arrays.sort if the had is an array, or Collections.sort if the hand is an ArrayList. Show the hands. Document, document, document!

I’m a coffee addict. So, when I wake up in the morning, I go into my kitchen, switch on the coffee machine and make coffee. Sounds familiar? I need to know how to use my coffee machine to make coffee. I need to provide water and coffee beans, switch it on and select the kind of coffee I want to get. The machine brew the coffee I demanded. I just interact with a simple interface that doesn’t require any knowledge about the internal implementation. I want you to prepare a software that runs the machine and provides me with the selected coffee. Only in c++ language
