Question

Write a program(In java) that lets the user enter four quarterly sales figures for six divisions of a company. The figures should be stored in a two-dimensional array. Once the figures are entered, the program should display the following data for each quarter: - A list of the sales figures by division - each division's increase or decease from the previous quarter (This will not be displayed for the first quarter) - The total sales for the quarter - The company's increase or decrease from the previous quarter (This will not be displayed for the first quarter) - the average sales for all divisions that quarter - the division with the highest sales for that quarter Also we have to enter the missing code from the Divisions class and SaleStatics Class as below: public class Divisions { private final int DIVISIONS = 6; // Number of divisions private final int QUARTERS = 4; // Number of quarters // Create an array to hold company-wide sales data. private double[][] sales = new double[DIVISIONS][QUARTERS]; /** * setSales method * This method sets a division's amount of sales for a * specified quarter. */ public void setSales(int div, int quarter, double amount) { /* Missing code starts here */ /* Missing code ends here */ } /** * getSales method * This method returns a division's sales for a specified * quarter. */ public double getSales(int div, int quarter) { // The array subscripts are zero-based, so subtract 1 // from div and quarter to get the correct subscript. return sales[div - 1][quarter - 1]; } /** * totalQuarterSales method * Returns the total sales for the specified quarter. */ public double totalQuarterSales(int quarter) { /* Missing code starts here */ /* Missing code ends here */ } /** * getQuarterlyIncrease method * Returns the quarterly increase for a specified * quarter, for a specified division. If the quarter * is 1, or if an invalid value is passed for the * quarter or the division, the method returns 0.0. */ public double getQuarterlyIncrease(int div, int qtr) { /* Missing code starts here */ /* Missing code ends here */ } } AND import java.io.*; import java.util.Scanner; import java.text.DecimalFormat; public class SalesStats { public static void main(String[] args) throws IOException { // Create a Divisions object.
