Question
Urgent help needed!! Thank you (Object-Orientated) Java Programming
Write a program to produce a sales commission report from a company’s sales file (sales.txt). Each record on the sales file contains the salesperson’s number, name and sales amount.
Your program is to read the sales file, calculate the sales commission according to the following table, and print a sales commission report.
Sales range
Commission rate
$0–$499.99
No commission
$500.00–$749.99
2%
$750.00 and above
3%
Each detail line is to contain the salesperson’s number, sales amount, commission rate and total commission. Print headings and column headings at the top of each page, allowing for 8 records per page, and at the end of the report, the total commission, as follows:
SALES COMMISSIONS PAGE: XX
SALESPERSON SALESPERSON SALES AMOUNT COMMISSION COMMISSION
NAME NUMBER RATE
xxxxx xxxxxxxxxxx 9999.99 x% 999.99
xxxxx xxxxxxxxxxx 9999.99 x% 999.99
TOTAL COMMISSION 9999.99
Use divide and conquer concept to split the program code into a set of customised methods such as printPageHeading, processSaleRecord, printLineItem(), printReportFooter and etc.
Sales range
Commission rate
$0–$499.99
No commission
$500.00–$749.99
2%
$750.00 and above
3%
