Write java program that asks the user to enter the service and the hours spent, then calculates and outputs the service charge.

You should use a flag-controlled or a sentinel-controlled while loop so that the program can get a series of sales data until the user enters 0. Inside the loop, a switch structure is used to help select a product and output the cost for each product.

Your program should also calculate and output the total service charges of each service, and the overall service charges of all services.
