The purpose of this assignment is to give you more experience in reading a short description of what we want a Java program to do and thinking your way through the program to write the program from scratch.

Write a Java program that welcomes the user and then prompts the user to enter a dollar amount for investment. Calculate a service charge of 3/10ths of a percent. Add the amount to the investment amount and display the three value.

The service charge amount should be declared as a constant, and the largest amount that can be invested is $99,999,999.99 (note: this is important for you to know when determining what the insertion sequence should be). Display the investment amount, service charge amount and total amount due rounded to exactly two decimal places and with a short message in front of each amount telling the user what is being displayed. Use printf and insertion sequences where necessary and place a short line of hyphens in between the service charge amount line and the total amount due line.

At the end, thank the user for using the program.

Here is example output in which the service charge is not arithmetically 3/10ths of a percent:

Welcome to NIU Investments!

Please enter the amount you would like to invest today: 34543.25

Total Investment (in dollars): 34543.25

Service Charge (in dollars): 22.33

-----------

Total Amount Due (in dollars): 34565.58

Thank you for your investment!
