- 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 CompareCarsByMakeThenDescendingMPG that can be passed as an argument to the quicksort method from the lecture notes.…Add a void instance method replaceAll(E oldE, E newE) in the MyLinkedList class to replace the occurrence of all oldE value with the specified newE value.

Assume that class T is Comparable.DO NOT USE ANY OTHER METHODS OF THE LINKED BASED LIST CLASS. What is the worst case and best case complexity of the code in the previous problem? Explain your answer.In java, Implement a method that removes all duplicates.

- 4. Now examine the ArrayList methods in the above table, a) Which method retrieves elements from the ArrayList? b) Which method replaces the value of an element that already exists in the ArrayList? c) Which two methods initializes the value of an element? d) How do the two methods in (c) differ? Which method(s) would be appropriate in the above Java program (after we convert it to work with ArrayLists)?Write a java program that uses an ArrayList object to store the following set of names in memory: [Steve, Tim, Lucy, Pat, Angela, Tom] Now write some more code so that the same ArrayList object is augmented with the name 'Steve' after the name 'Lucy' After the ArrayList object has been augmented with the new name, display the original and new lists on the console (as shown below), to verify that the new name is positioned correctly in the list.The split method in the String class returns an array of strings consisting of the substrings split by the delimiters. However, the delimiters are not returned. Implement the following new method that returns an array of strings consisting of the substrings split by the matching delimiters, including the matching delimiters. public static String[] split(String s, String regex) For example, split("ab#12#453", "#") returns ab, #, 12, #, and 453 in an array of String and split("a?b?gf#e", "[?#]") returns a, ?, b, ?, gf, #, and e in an array of String.
- Write a method replace to be included in the class KWLinkedList (for doubly linked list) that accepts two parameters, searchItem and repItem of type E. The method searches for searchItem in the doubly linked list, if found then replace it with repItem and return true. If the searchItem is not found in the doubly linked list, then insert repItem at the end of the linked list and return false. Assume that the list is not empty. You can use ListIterator and its methods to search the searchItem in the list and replace it with repItem if found. Do not call any method of class KWLinkedList to add a new node at the end of the list. Method Heading: public boolean replace(E searchItem, E repItem) Example: searchItem: 15 repItem: 17 List (before method call): 9 10 15 20 4 5 6 List (after method call) : 9 10 17 20 4 5 61 IN JAVA ----- Write a method of public class called "isInputOneValid" that verifies if a string parameter called "inputOne" is included inside an array called "tableOne".
