Create a class named Calculate2. Add 2 instance variables, Quantity and UnitPrice. UnitPrice can include Rupees andCents.3. Add a no-argument constructor and a parameterized constructor.4. Add getters and setters for the 2 instance variables5. Add a user defined method named Total with no arguments. Total will calculate andreturn Quantity*UnitPrice. If Quantity is greater than 10, give 5% discount.6. Add a user defined method to display the total amount to the user.7. Create a Java Main application to create 2 objects using both constructors based onthe Calculate class to test the program.

- Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four information as instance variables: a part number (type String), a part description (type String), a quantity of the item being purchased (type int) and a price per item (double). Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0. Write a tester class named InvoiceTest that demonstrates class Invoice’s capabilities by creating two invoices then changing and printing their characteristics.arrow_forwardThe Rectangle class) Following the example of the Circle class in Section 9.2, design a class named Rectangle to represent a rectangle.

- Create a class called Complex for performing arithmetic with complex numbers. Complex numbers have the form realPart + imaginaryPart * i where i is -1 Write a program to test your class. Use floating-point variables to represent the private data of the class. Provide a constructor that enables an object of this class to be initialized when it is declared. Provide a no-argument constructor with default values in case no initializers are provided. Provide public methods that perform the following operations: a) Add two Complex numbers: The real parts are added together and the imaginary parts are added together. b) Subtract two Complex numbers: The real part of the right operand is subtracted from the real part of the left operand, and the imaginary part of the right operand is sub- tracted from the imaginary part of the left operand. c) Print Complex numbers in the form (a, b), where a is the real part and b is the imaginary part.arrow_forward(The Rectangle class) Following the example of the Circle class in Section 8.2,design a class named Rectangle to represent a rectangle.
