Chapter 10, Problem 1E
Create an application class named LetterDemo that instantiates objects of two classes named Letter and CertifiedLetter and that demonstrates all their methods. The classes are used by a company to keep track of letters they mail to clients. The Letter class includes auto-implemented properties for the name of the recipient and the date mailed. Also, include a ToString() method that overrides the Object class’s ToString() method and returns a string that contains the name of the class (using CetType and the Letter’s data field values. Create a child class named CertifiedLetter that includes an auto-implemented property that holds a tracking number for the letter.

1. Dummy GUI Application
by Codechum Admin
A GUI Application is an application that has a user interface that the user can interact with. For this program, we will be simulating this behavior.
First, implement another class called Checkbox which implements the Clickable interface which has only one method: public void click(). The Checkbox will have the following properties:
private boolean isChecked (defaults to false upon the creation of object)
private String text
Additionally, it should have the following methods:
the implementation of the click() method
If the isChecked is currently false, this will set the isChecked to true and will then print the message "Checkbox is checked". If it is currently true, this will set the isChecked to false and will then print the message "Checkbox is unchecked". Note that the messages to be printed should have also print a new line at the end.
an override of the toString() method which returns the message: "Checkbox ({text} - Clicked…

This field must be private since users presumably can’t change this value. Have two constructors: one that initializes everything to some default value for the base price of a car and one that also accepts values for luxury upgrades of: heated seats, sun-roof, and satellite radio. The class has two methods: 1) Get Paint Color() which accepts a standard base color option but allows the user to purchase a pricier customized color 2) Upgrade Costs() which computes the cost of user-selected luxury items and adds it to the price. Create three car objects: Ford (make Explorer), Lexus (make ES) and a Clown Car which overrides the passenger value to allow 20 clowns in the car.
