I need the softcode (no hardcode) for the following problem:

Consider a program that will read employee data, sort the data by employee identification number, write out the sorted data, and compute various statistics about the data, such as the average age of an employee. Design a modular solution to this problem using UML notation. What classes and methods did you identify during the design of your solution? Write complete specifications, including preconditions and postconditions, for each module.

Additionally, write the class and function descriptors (without actually implementing the functions) along with comments for documentation.
