I'm not really sure how to answer the question below. There are two question. Any help would be appreciated.
Problem:
Consider a program that will read employee information into an array of objects, sort the array by employee identification number, write out the sorted array, and compute various statistics on the data, such as the average age of an employee.
Part 1 :-) Write complete specifications for this problem and design a modular solution. What classes and methods did you identify during the design of your solution?
Part 2 :-) Write specifications, including preconditions and post-conditions, for each method. Write specifications for a function that advances any given date by one day.
Answer with detail.
