Define a class Car as follows: class Car { public String make; public String model; public int mpg; // Miles per gallon } c) Implement a comparator called CompareCarsByMakeThenDescendingMPG that can be passed as an argument to the quicksort method from the lecture notes. CompareCarsByMakeThenDescendingMPG should return a value that will cause quicksort to sort an array of cars in ascending order by make and, when two cars have the same make, in descending order by mpg.
- Can you implement the Student class using the concepts of encapsulation? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. You are given a Student class in the editor. Your task is to add two fields: ● String name ● String rollNumber and provide getter/setters for these fields: ● getName ● setName ● getRollNumber ● setRollNumber Implement this class according to the rules of encapsulation. Input # Checking all fields and getters/setters Output # Expecting perfectly defined fields and getter/setters. There is no need to add constructors in this class.Please complete the task by yourself only in JAVA with explanation. Don't copy. Thank you. Only finish the (d) question, Thank you !
