Write а cоmplete Jаvа prоgram named CalculateCоst. It receives the name of a customer as a console argument. It then prints a welcome message and asks for the number of products the customer is buying. After that, it accepts a list of products (one per line) that the customer wishes to buy. The product options a user can enter per line are "pen" or "pencil". A pen costs $2, and a pencil costs $1.25. The program prompts for products until it has received the exact number of products provided by the user in the first prompt. After the list, the program prints the final line with the cost after taxes (the tax is 4% of the cost before tax). The cost should be rounded to two decimals. Your output must look exactly like the example. The final line must be printed in its entirety with a single printf Example command: java CalculateCost Max. Example console input/output (input in bold):Hello Max!Please enter the number of products: 3pencilpenpencil
