I need help with completing my Unit 3 assignment in Introduction to Programming : Java The assignment in detail is as follows:

LiFiUnit3.java – Main Method

Program should read in a file called “sales.txt”. The contents of the text file are below.

Read in all data from the file. (refer to pages 102-103)

  • Sore units in integers and store sales in doubles.
  • The first integer is the first unit sales. The first double is the first $ of all the sales combined.
  • This continues through all five units.

Utilize a constant called taxRate to hold the tax rate of 8.5%.

Output the following items per the sample below:

  • Total Unit Sales (the sum of all units)
  • Total Sales (the sum of all sales)
  • Total Tax (rounded) (sales times taxRate)
    • Type cast to int * 100, then double / 100.
  • Total Sale (not rounded) (sales plus tax)
  • Output results in table format using the escape character for a tab as shown in the sample.

Round the sales tax using basic math to round it. Do NOT use printf or any rounding function to perform this.

The sales.txt file contains these 5 values:

14       128.5612       102.459          93.8713        114.077          89.34 

Ofcourse I would love for someone to just help me get the assignment done, but what I really wish is that I understood what to do, and how to actually do this assignment. I have been reading (and absorbing) as much as I can but it just doesn’t seem to make the difference. 

Please help!!
