You are developing a class named ShoppingCart to handle an online grocery store. The ShoppingCart class includes three overloaded methods named calculateTotal$()$ for computing the total bill.

i$)$ The first calculateTotal$()$ method takes a single parameter, which represents the price of a single item in the shopping cart. It should calculate and return the total due after adding an $8\%$ tax.

ii$)$ The second calculateTotal$()$ method takes two parameters, representing the price of an item and the quantity ordered. It should calculate and return the total due by multiplying the price and quantity, adding an $8\%$ tax.

iii$)$ The third calculateTotal$()$ method takes three parameters, representing the price of an item, the quantity ordered, and a discount percentage. It should calculate and return the total due by multiplying the price and quantity, applying the discount percentage, adding an $8\%$ tax.

Write a main$()$ method to test all three overloaded calculateTotal$()$ methods
