Define a class Car as follows: class Car { public String make; public String model; public int mpg; // Miles per gallon } a) Implement a comparator called CompareCarsByMakeThenModel that can be passed as an argument to the quicksort method from the lecture notes. CompareCarsByMakeThenModel should return a value that will cause quicksort to sort an array of cars in ascending order (from smallest to largest) by make and, when two cars have the same make, in ascending order by model. b) Implement a comparator called CompareCarsByDescendingMPG that can be passed as an argument to the quicksort method from the lecture notes. CompareCarsByDescendingMPG should return a value that will cause quicksort to sort an array of cars in descending order (from largest to smallest) by mpg. c) Implement a comparator called…Please complete the task by yourself only in JAVA with explanation.

Instead of storing the choices in an array list, the addChoice method should add the choice to the question text. For this purpose, an addLine method has been added to the Question class. Use the following files: Question.java /** A question with a text and an answer.*/public class Question{ private String text; private String answer; /** Constructs a question with empty text and empty answer. */ public Question() { text = ""; answer = ""; } /** Sets the answer for this question. @param correctResponse the answer */ public void setAnswer(String correctResponse) { answer = correctResponse; } /** Checks a given response for correctness. @param response the response to check @return true if the response was correct, false otherwise */ public boolean checkAnswer(String response) { return response.equals(answer); } /** Add a line of text to…

The program should then print out the elements initially in the original order, and then afterwards in reverse order using the ListIterator methods. In this case, the following is the expected output:

There are two ways to give the sort method the code to compare objects,implementing the interfaces Comparable and Comparator respectively. Extend Article class toimplement Comparable interface so that the default sorting of the Articles is by its volumeWrite a java static method indexShortest() that takes an array of strings as a parameter, returns the index of the shortest string in that array.Do not write the whole program, write only the method. Do not use Collections and Arrays classes methods. Use necessary loops. please solve it ASAP!

Implement a method that will return a String with an array's elements separated by spaces. The mehod will recieve three parameters: the integer array, a start index, and an end index. Both start and end are includive. The method's signature is as follows: public static String printRange(int [], int, int) - make the method public to faciliate testing - If the indexes are outside the bounds of the array, the method should return "Invalid Range." Otherwise, the method will return a String containing one integer after the other on the same line separated by one space. Example 1: Given {4,1,2,36,6}, 1, 3 as the parameters; the method should return "1 2 36" Example 2: Given {4,1,2,36,6}, 0, 7 as the parameters; the method should return "Invalid Range"Create an arraylist in Java of 10 students. Use the following methods: add, remove, insert, size, capacity, contains ,and clear
