java

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 station location, the quantity of purchase in litres, the type of petrol, the price per litre and the percentage of discount. Your class should have a constructor that initiates the five instance variables and a copy constructor to duplicate the objects. Provide a set and a get method for each instance variables (even my UML diagram didn't show all of them ...). In addition, include a method called getPayment that gets the net purchase amount computed in the computePayment method. Write a java program with two classes (see UML diagram) defined in one class and PetrolPurchase another independent class. The following shows the interactions: Enter the station: Bukit Timah Enter quantity in liter: 25.5 Enter type of petrol: Super 99 Enter price of petrol: 3.55 Enter discount: 15 The system displays the following summary purchased: Summary of your purchase Station: Bukit Timah Total liter: 25.50 Petrol type: Super 99 Price per liter: 3.55 Actual cost: 90.52 Discount (156): 9.05 Amount to pay: 76.95 The customer decides to add in some for more litres of petrol: Enter addtional quantity of petrol: 10.5 Your new purchased price Station: Bukit Timah Total liter: 36.00 Petrol type: Super 99 Price per liter: 3.55 Actual cost: 127.80 Discount (159): 12.78 Amount to pay: 108.63 The company usually give a duplicate copy to customer. Invoke the copy constructor to have this duplicate copy: Duplicate the same object Station: Bukit Timah Total liter: 36.00 Petrol type: Super 99 Price per liter: 3.55 Actual cost: 127.80 Discount (158): 12.78 Amount to pay: 108.63 The following shows the UML diagram of the two classes: Lab_3 PetroPurchase 5-static Scanner input **static void mainiStringi args) -String station - double quantity - String type - double price - int discount +Petrolpurchase(Strings, double 4.
