Prerequisite: Read what an API is in the textbook Introduction to Programming Using Java by David J. Eck on pages 142−143.
When solving the problems in this section, you must follow the application programming interface (API) expected in each problem. You should implement all the attributes and operations mentioned in the API.
Note that there is no main method in the APIs. That is, you should not perform any data processing within the main method. You should rather use the main method to test other methods, prompt the user for some inputs, and display the results returned by your methods.
