Employee’s Payroll System that Display Highest and Lowest Salary in Java

Here is the code that is being shared with us by my good friend and fellow software engineer Sir Jake Macalig-og which I modify and improve that will compute the salary of the employees and sort the salary of the employees from highest to lowest. We wrote this code will some difficulty because there is no existing code on the Internet so we have to write it from scratch.
