Java Program Calculator.. Need in 1 hour

Write a Java™ application using NetBeans™ Integrated Development Environment (IDE) or jGROUP IDE that calculates the total annual compensation of a salesperson.

Consider the following factors:
The calculator should allow user to enter the amount of sales.

The calculator should allow user to select the percent of commission rate from a list of pre-defined commission rate.

The 5 choices in the list are:
• <2%>
• <4%>
• <6%>
• <10%>
• <15%>
The calculator should display the amount of commission (in dollars), based on the amount of sales entered and the commission rate selected and the total annual compensation.

The Java™ application should meet these technical requirements:

• The application should have at least one additional method, 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.
• You do not need to create a GUI for this program.
