The document provides instructions to create two Java classes: 1) A Bill class with fields for number, name, and amount, and constructors to set their values. It also includes get/set methods and a toString() method. 2) A TestBill class with a main method that creates two Bill objects using different constructors, prints them, prompts the user for input, calls calculateTax on both objects, and prints the results.

1. Instructions Write a class named Bill with the following specifications: - The class contains
three fields, one of type int named number, one of type String named name, and one of type
double named amount. - The class contains one constructor which has parameters for all fields.
The constructor should set the values of the fields to the values passed to its parameters. - The
class should contain another constructor which has only one parameter for the name field. The
constructor should set. the value of the name field to the value passed to its parameter. The
constructor should set the number field to 999 . The constructor should set the value of the
amount field to 0.0 . - The class contains get and set methods for each field. - The class contains
a toString() method that returns a String that contains information about the value of all fields.
Double values should be rounded to two decimal places. - The class contains a method named
calculateTax with return type double and one parameter of type double named percentage. The
method should return the value of the amount field multiplied by the value of percentage. Write
another class named TestBill with the following specifications: - The class contains a main()
method. - The class creates two Bill objects each using a different constructor. - The class uses
two System.out.printin() statements to print the objects without using the get methods. - The
class should prompt the user to enter a double value. - The class should save the user input in a
variable. - The class should call the calculateTax method for both objects, passing the value input
by the user to the method. - The class should print the results of the method calls to the screen.
