Create a class called PetrolPurchase to represent information about the petrol you purchase. The class should include five pieces of information in the form of instance variables:

The stations location (type String),

The type of petrol (type String),

The quantity (type int) of the purchase in liters, The price per liter (double),

The percentage discount (double).

Provide a set and a get method for each instance variable. In addition, provide a method named getPurchaseAmount that calculates the net purchase amount (i.e., multiplies the quantity by the price per liter) minus the discount, then returns the net amount you had to pay as a double value. Write an application class named Petrol that demonstrates the capabilities of class PetrolPurchase.
