Create a class that will bundle together several static methods for tax computations. This class should not have a constructor. Its attributes are

• basicRate—the basic tax rate as a static double variable that starts at 4 percent
• luxuryRate—the luxury tax rate as a static double variable that starts at 10
percent
Its methods are
• computeCostBasic(price)—a static method that returns the given price
plus the basic tax, rounded to the nearest penny.
• computeCostLuxury(price)—a static method that returns the given price
plus the luxury tax, rounded to the nearest penny.
• changeBasicRateTo(newRate)—a static method that changes the basic tax
rate.
• changeLuxuryRateTo(newRate)—a static method that changes the luxury
tax rate.
• roundToNearestPenny(price)—a private static method that returns the
given price rounded to the nearest penny. For example, if the price is 12.567, the method will return 12.57.
