Question
?Develop a Java Program to solve the given problem.
The Denver Urban Sports Technicians (DUST) rent and sell recreational equipment including canoes, bikes, windsurfers, and trailers. The accountant for DUST requires a monthly supplier report. A number of suppliers are used and each sells equipment to DUST on a credit basis and charges DUST interest on the final monthly balance owed to the supplier. The transactions with each supplier are tracked over the month on a Supplier Transaction Sheet. The Supplier Transaction Sheet first lists the month the transactions occurred. Then for each supplier the Transaction Sheet lists the supplier name, the balance forward (balance owed to supplier for previous purchases) and the monthly interest rate. The supplier 's entry is followed by all the transactions related to the supplier for that month. Each transaction includes the transaction number, type and amount. DUST requires a monthly report to show all the information seen on the Supplier Transaction Sheet. Additionally at the end of each transaction record the report must display the current balance. And after each supplier 's last transaction the report must display the amount of monthly; interest due and the ending balance owed to the supplier. Also after all suppliers are processed a report summary must show the overall balance, the average purchases per supplier for the month, the total monthly payments, the highest supplier final balance and the name of the supplier owed this balance. In the case of multiple instances of the highest only report the first instance. All numeric values listed in the summary arExplanation / Answer
