Please write a Java program, named Sales.java for a computer store. In this program, user is asked to input the price of a computer and the numbers of this kind computers have been sold through keyboard. Then the computer will automatically compute the amount of money that this store gets by selling computers (the amount of money = price per computer * the number of computers that have been sold) and display this amount of money on screen.

From: How to Think Like a Computer Scientist: Learning with Python 3 -Chapter 6, Exercise 9 Write three functions that are the “inverses” of to_secs: (a) hours_in returns the whole integer number of hours represented by a total number of seconds. (b) minutes_in returns the whole integer number of left over minutes in a total number of seconds, once the hours have been taken out. (c) seconds_in returns the left over seconds represented by a total number of seconds.   My original  to_secs function: def to_secs(h, m, s): total = 0 total = total + h * 60 * 60 total = total + m * 60 total = total + s return total

4.Rohan bought a gallon of milk with an original price of $4.25; today he gets a 15% discount before a 5% tax; display the final price of the milk.5.This function is named compound_interest, takes these arguments p r n t; compute and return a for displaya = p (1 + r/n) nt6.This function is named annuities, takes these arguments r i n; compute and return s for displays = r ((1 + i)^(n + 1))/i - r

Fix the following function prototype so that the variables are passed by reference, then write the function below. void swap(double x, double y); Hint: be consistent with your style.
