 * Description:
    •	Define a static method called printSalary to print hourly salaries. The 
        printSalary method should take a double array as an input.
    •	Define an instance method called averageSalary to return average hourly 
        salary.
    •	Define an instance method called highestSalary to print the highest 
        hourly salary.
    •	Define an instance method called lowestSalary to print the lowest hourly
        salary.
    •	Define an instance method called belowAverageSalary to return the number
        of employees with less than the average hourly salary.
