Need help to compare with my code.

Write a Vehicle class. An automobile has a year and manufacturer. Implement at least one constructor that takes a year and manufacture name.

Write a Car class. A car is a vehicle but also has a MPG. A car is comparable based on their MPGs. Implement at least one constructor that takes year, manufacturer and MPG, and the method for comparing cars.

In the main method, create a list of 3 cars of your choice, then sort the cars by their MPGs. Also in the main method, create an array of 3 cars of your choice, then sort the cars by their manufacturers names. You must use a comparator this time, and use the anonymous inner class style.

Finally, sort the cars by their years using lambda expression style.
