How do I write this java program
Write a simple java program to be used by a shopkeeper in Kisii. Once a customer visits a shop & Identifies items to buy, the attendant totals up the price of the goods and informs the customer cost of all goods. The customer tenders in the amount of money which is normally more that the cost of the goods. Once the attendant receives the tendered amount, he/she calculates the change and then hands over the goods plus the change to the customer. You are required to write a java class (ComputeChange.java) with the main method which takes in the total cost of goods, and the amount tendered by the customer. The application should compute and return the change to be given to the customer. The application should also print out a receipt for the customer.
