Calculate salary: Generalize a program with variables and input.

The following program uses a variable workHoursPerWeek rather than directly using 40 in the salary calculation expression.

1. Run the program, observe the output. Change 40 to 35 (France's work week), and run again.
2. Generalize the program further by using a variable workWeeksPerYear. Run the program. Change 50 to 52, and run again.
3. Introduce a variable monthlySalary, used similarly to annualSalary, to further improve program readability.

public class Salary { public static void main(String[] args) { int hourlyWage; int workHoursPerWeek; int annualSalary;

// FIXME: Declare and initialize variable workWeeksPerYear, then replace the 50's below

hourlyWage = 20; workHoursPerWeek = 40; annualSalary = hourlyWage * workHoursPerWeek * 50; System.out.print("Annual salary is: "); System.out.println(annualSalary); System.out.print("Monthly salary is: "); System.out.println((hourlyWage * workHoursPerWeek * 50) / 12); } }
