Encapsulation:

• It combines the data and code into a single object.

• It helps in restricting access to the methods.

• This helps in preventing the data from being modified due to accident.

• The object’s variable is not directly accessible.

• Underscore helps in preventing the data from being accessed directly.

The encapsulation rules in Python can be summarized as follows:

Public method It is accessible from anywhere.
Public variables It can be accessed from anywhere.
Private method It can be accessed only in their own class
Private method It is accessible only in their class or method.

• It protects the data from tampering. By declaring the data field as private, direct modifications of properties are prevented.

• It makes the class easy to maintain and reduces the errors...

Write a FancyCar class to support basic operations such as drive, add gas, honk horn, and start engine. FancyCar.java is provided with method stubs. Follow each step to gradually complete all methods. Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. The main() method includes basic method calls. Add statements in main() as methods are completed to support development mode testing. Step 0. Declare private fields for miles driven as shown on the odometer (int), gallons of gas in tank (double), miles per gallon or MPG (double), driving capacity (double), and car model (String). Note the provided final variable indicates the gas tank capacity of 14.0 gallons. Step 1 (2 pts). 1) Complete the default constructor by initializing the odometer to five miles, tank is full of gas, miles per gallon is 24.0, and the model is "Old Clunker". 2)…
