Reasons for displaying the given output:

• From the given code of “ExerciseProgram”

○ The variable “s1” is the object of “Species” class.

○ The variable “mysteryMaker” is the object of “ExerciseClass” class.

○ The statement “int n = 0;” implies initializes the variable “n” to “0”.

○ The statement “s1.setSpecies("Hobbit", 100, 2);” implies call the method “setSpecies” for object “s1” with arguments of “Hobbit” for name, “100” for population and “2” for growth rate.

■ Now “s1” contains “Hobbit” for name, “100” for population and “2” for growth rate.

○ The statement “mysteryMaker.mystery(s1, n)” implies call the method “mystery” for object “mysteryMaker” with arguments of “s1” for “Species” class and “n”.

■ In the “ExerciseClass” class, the method “mystery” implies

• Call the method “setSpecies” for object “s” with arguments of “Klingon ox” for name, “10” for population and “15” for growth rate...

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)…
