Program plan: - Use the packages and define the namespaceConferenceApplication . Define the class ConferencesDemo, inside the class define the main method. Create an instance of 5 Conference objects. Use the loop to read the 5 Conference objects in the list. Call the Sort method to sort the list. Use the loop to print sorted conference by number of attendees. Define the namespace ConferenceApplication . Define the class Conference and implement the interface IComparable . Declare the variables as per the requirement. Define the parameterized constructor to initialize the variables. Use the property to implement the getters and setters. Override CompareTomethod .

The conference class consists of data members group name, starting date, and the number of attendees. Also, include theIComparable.CompareTo () method to sort the Conference objects.

Question

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)…
