Individual Assignment: Simple Commission Calculation Program Part 1 Write a Java™ application using NetBeans™ Integrated Development Environment (IDE) that calculates the total annual compensation of a salesperson. Consider the following factors: • A salesperson will earn a fixed salary of $50,000 • A salesperson will also receive a commission as a sales incentive. Commission is a percentage of the salesperson’s annual sales. The current commission is 5 % of total sales. • The total annual compensation is the fixed salary plus the commission earned. The Java™ application should meet these technical requirements: • The application should have at least one class, in addition to the application’s controlling class (a controlling class is where the main function resides). • There should be proper documentation in the source code. • The application should ask the user to enter annual sales, and it should display the total annual compensation.
