a. Write a Java class that declares a named constant that represents next year’s anticipated 10 percent increase in sales for each division of a company. (You can represent 10 percent as 0.10.) Also declare variables to represent this year’s sales total in dollars for the North and South divisions. Assign appropriate values to the variables—for example, 4000 and 5500. Compute and display, with explanatory text, next year’s projected sales for each division. Save the class as ProjectedSales.java.

b. Convert the ProjectedSales class to an interactive application. Instead of assigning values to the North and South current year sales variables, accept them from the user as input. Save the revised class as ProjectedSalesInteractive.java.
