Assignment:
In the real world, an entire program is rarely written from scratch. It is very likely that there are classes or functions that already exist. The key to using these existing modules successfully depends on how modular the classes or functions are written.
In this assignment, your mission is to replace the CommissionCalculator of your Week Three program with the CommissionCalculatorMjf class I have attached.
1. To see the documentation (javadoc) of this class, click the link on the right.
2. This class is attached in a Java "jar" file; see the link on the right.
a. Once you download the zip file, rename it, changing the extension from zip to jar.
b Then, in your NetBeans project, right-click on the "Libraries" folder and choose "Add JAR/Folder...". Then find the jar file and choose it.
c. Put the following statement in your Java application class file, near the top:import CommissionCalculatorMjf.
d. Now you can use the class, like this:CommissionCalculatorMjf myCalc = new CommissionCalculatorMjf( rate );
