In kotlin, write code of that creates a list of strings that can be null.

File TesSLL.java contains a driver that allows you to experiment with these methods. Compile and run TestSLL, and play around with it to see how it works. Then add the following methods to the SinglyLinkedList class. For each, add an option to the driver to test it. Do this in incremental steps!! This means, implement and test the methods one at a time.

Instructions Write a program to test various operations of the class doublyLinkedList. Your program should accept a list of integers from a user and use the doubleLinkedList class to output the following: The list in ascending order. The list in descending order. The list after deleting a number. A message indicating if a number is contained in the list. Output of the list after using the copy constructor. Output of the list after using the assignment operator. An example of the program is shown below: Enter a list of positive integers ending with -999: 83 121 98 23 57 33 -999 List in ascending order: 23 33 57 83 98 121 List in descending order: 121 98 83 57 33 23 Enter item to be deleted: 57 List after deleting 57 : 23 33 83 98 121 Enter item to be searched: 23 23 found in the list. ********Testing copy constructor*********** intList: 23 33 83 98 121 ********Testing assignment operator*********** temp: 23 33 83 98 121 Your program should use the value -999 to denote the end of the…

In the following program skeleton, replace the < insert code here> line with theappropriate code. The resulting program should display the initial list of songs,prompt the user for a string of text to be replaced and then prompt for new text toreplace it. After making the replacement, it should display the updated list of songs.import java.util.Scanner;public class UpdateSongs{public static void main ( String [] args){Scanner stdIn = new Scanner(System.in);String songs =“ 1. Welcome to Your Life – Grouplove\n” +“ 2. Sedona – Houndmouth\n” +“3. Imagine – John Lennon\n” +“4. Bohemian Rhapsody –Queen\n”;String oldText, newText;< insert code here>}}Sample Session:1. Welcome to Your Life – Grouplove”2. Sedona – Houndmouth3. Imagine – John Lennon4. Bohemian Rhapsody –QueenEnter text to replace: LennonEnter new text: Dean1. Welcome to Your Life – Grouplove”2. Sedona – Houndmouth3. Imagine – John Dean4. Bohemian Rhapsody –Queen

// The language is java, please take a screenshot of your output, and make sure your code is run.

To declare an array of String called myStrings, we would code: ArrayList<Blank 1> myStrings = Blank 2 ArrayList<String>();

Create class Test in a file named Test.java. This class contains a main program that performs the following actions: Instantiate a doubly linked list. Insert strings “a”, “b”, and “c” at the head of the list using three Insert() operations. The state of the list is now [“c”, “b”, “a”]. Set the current element to the second-to-last element with a call to Tail() followed by a call to Previous()Then insert string “d”. The state of the list is now [“c”, “d”, “b”, “a”]. Set the current element to past-the-end with a call to Tail() followed by a call to Next(). Then insert string “e”. The state of the list is now [“c”, “d”, “b”, “a”, “e”] . Print the list with a call to Print() and verify that the state of the list is correct.
