Answer 1

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

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