JAVA CODE

Question 2. (30 points) A supermarket wants to keep statistical data about its customers. For that purpose, they want you to write the following java program: a) (10 pts.) In this first part your code will prompt the cashier to enter all names and prices. Your code will take names to a string array list and prices to double array list. (Hint: Because of a Java bug, you may need to use two scanner objects, one for string and char input, and one for double input) b) (10 pts.) Write a method to calculate the average, and standard deviation of the customer prices. This method takes the prices as input and prints the average and standard deviation. Average = (price 1 + price2 + ...+priceN)/N (Total number of customers). Standard deviation = sqrt ((price1 - average)2 + (price2 - average)2 + ..+ (priceN-average)2/N (Total number of customers)). c) (10 pts.) Sort customer names alphabetical order (from "A" to "Z"). Do not forget to change their prices' position according to new ordering
