Total Calculation

Objective

Task

Your task for this lab is to write a program that reads in a number of floating point values from a file, adds them together, and then prints out the total.

It must also print out the sales tax on the total at a 5.3% rate, and the final total of the original items + sales tax.

The input is from a file called "items.txt" and the output should be to a file called "total.txt".

Details

• Open the "items.txt" file.
• Read all of the values in a loop. You will need to use "hasNextDouble" for this.
• Keep a running total of the numbers in the file.
• Calculate the sub-total, tax, and final total.
• Write them out to the "total.txt" file.
• Print only two decimal points as these are monetary values.

Sample Files

Here is a sample items.txt file.

Here is the output that should appear in total.txt.
