Write a Java program that will create a report to display the top three mobile device sales per month
from January to March 2018. The rows and columns represent the monthly sales of each device.
JAN FEB MAR TOTAL
IPhone 7 30 15 35 80
Samsung S8 20 25 30 75
Huawei Mate 10 25 11 32 68
MONTHLY TOTAL 75 51 97
Using a Two-Dimensional array, produce the monthly mobile device sales report and the total sales
for each device.

Answer 1

public class Main {


	public static void main(String[] args) {
		String[] monthsNames = { "DEVICE", "JAN", "FEB", "MAR", "TOTAL" };
		String[] deviceNames = { "IPhone 7", "Samsung S8", "Huawei Mate 10" };
		int[][] monthlySales = { { 30, 15, 35, 80 }, { 20, 25, 30, 75 }, { 25, 11, 32, 68 } };
		int[] monthlyTotal = { 75, 51, 97 };
		for (int i = 0; i < monthsNames.length; i++) {
			if (i == 0) {
				System.out.printf("%-17s ", monthsNames[i]);
			} else {
				System.out.printf("%-8s ", monthsNames[i]);
			}
		}
		System.out.println();
		for (int i = 0; i < monthlySales.length; i++) {
			System.out.printf("%-17s ", deviceNames[i]);
			for (int j = 0; j < monthlySales[i].length; j++) {
				System.out.printf("%-8s ", monthlySales[i][j]);
			}
			System.out.println();
		}


		System.out.printf("%-17s ", "MONTHLY TOTAL");
		for (int i = 0; i < monthlyTotal.length; i++) {
			System.out.printf("%-8s ", monthlyTotal[i]);
		}
	}
}
