CPU (Central Processing Unit): CPU is a part of the computer which actually runs the program . It is the most important component because without CPU, we cannot run any software. In olden days, they were like huge devices which were made up of electrical and mechanical components like vacuum tubes and switches. ENIAC (Electronic Numerical Integrator and Calculator) is considered as the world’s first programmable electronic computer which is 8 feet tall and 100 feet long. But, nowadays it is replaced by microprocessors. Operations performed by CPU: It performs operations such as, Reading a piece of data. Performing operations such as addition, multiplication, subtraction, and division of numbers. Moving a piece of data from one location to another location. These operations can be performed with the help of 0’s and 1’s. This is because CPU can understand only the instructions that are written in machine language.

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)…
