Question

A corporation has two divisions, each responsible for sales to different geographic locations. Design a DivSales class that keeps sales data for a division, with the following members: • An array with two elements for holding two halves of sales figures for the division. • A private static variable for holding the total corporate sales for all divisions for the entire year. • A member function that takes two arguments, each assumed to be the sales for a half year. The value of the arguments should be copied into the array that holds the sales data. The total of the two arguments should be added to the static variable that holds the total yearly corporate sales. • A function that takes an integer argument within the range of 0 to 1. The argument is to be used as a subscript into the division half-yearly sales array. The function should return the value of the array element with that subscript. Write a program that creates an array of two DivSales objects. The program should ask the user to enter the sales for two half-year for each division. After the data is entered, the program should display a table showing the division sales for each half-year. The program should then display the total corporate sales for the year.

       for(int i=0;i<arr.length;i++)
       {
           System.out.print("Division#"+(i+1)+" Sales:"+arr[i].getHalfYearSalesData(0)+"\t"+arr[i].getHalfYearSalesData(1)+"\n");
       }
      
       System.out.println("Total Corporate Sales :$"+DivSales.getTotalCorporateSales());
      

   }

}

Output:

Enter division 1 sales of first half year :$4500
Enter division 1 sales of second half year :$6500
Enter division 2 sales of first half year :$2300
Enter division 2 sales of second half year :$7800
Division#1 Sales:4500   6500
Division#2 Sales:2300   7800
Total Corporate Sales :$21100
