- Question 2: Linked List Implementation You are going to create and implement a new Linked List class. The Java Class name is "StringLinkedList". The Linked List class only stores 'string' data type. You should not change the name of your Java Class. Your program has to implement the following methods for the StringLinked List Class: 1. push(String e) - adds a string to the beginning of the list (discussed in class) 2. printList() prints the linked list starting from the head (discussed in class) 3. deleteAfter(String e) - deletes the string present after the given string input 'e'. 4. updateToLower() - changes the stored string values in the list to lowercase. 5. concatStr(int p1, int p2) - Retrieves the two strings at given node positions p1 and p2. The retrieved strings are joined as a single string. This new string is then pushed to the list using push() method.2. Linked ListsCreate a class called OurLinkedList and implement the following methods:1- Write a method called add() that takes a linked list of integers along an integerand adds that integer to the list.2- Write a method called print() that takes a linked list of integers and prints all itselements.3- Write a method called deleteAll() that takes a linked list of integers along an integer which deletes all the occurrences of this number in the linked list. So if the item is 7 and the list is [1,3,7,4,3,7,2], the result is [1,3,4,3,2].4- Write a method called indexesOf() that takes a linked list of integers along withan integer and returns a list of the positions of all the occurrences of that integer.So if the integer is 5 and the list is [2,4,5,8,1,5,3], the result is [2,5].· Write a method to insert an element at index in a Doubly Linked List data structure and test it. The method receives this list by parameters. * in java
- Lab 17 Using a linked list with an iterator Build a class called LinkedListRunner with a main method that instantiates a LinkedList. Add the following strings to the linked list: aaa bbb cc ddd eee fff ggg hhh iii Build a ListIterator and use it to walk sequentially through the linked list using hasNext and next, printing each string that is encountered. When you have printed all the strings in the list, use the hasPrevious and previous methods to walk backwards through the list. Along the way, examine each string and remove all the strings that begin with a vowel. When you arrive at the beginning of the list, use hasNext and next to go forward again, printing out each string that remains in the linked list.PYTHON LAB: Inserting an integer in descending order (doubly-linked list) Given main.py and an IntNode class, complete the IntList class (a linked list of IntNodes) by writing the insert_in_descending_order() method to insert new IntNodes into the IntList in descending order.

If the input is: 3 4 2 5 1 6 7 9 8 the output is: 9 8 7 6 5 4 3 2 1 _____________________________________________________________________________________ Main.py: from IntNode import IntNode from IntList import IntList if __name__ == "__main__": int_list = IntList() input_line = input() input_strings = input_line.split(' ') for num_string in input_strings: # Convert from string to integer num = int(num_string) # Insert into linked list in descending order new_node = IntNode(num) int_list.insert_in_descending_order(new_node) int_list.print_int_list() IntNode.py class IntNode: def __init__(self, initial_data, next = None,…Lab 17 Using a linked list with an iterator Build a class called LinkedListRunner with a main method that instantiates a LinkedList.

- java Create a static method that: is called removeAll returns ArrayList<String> takes two parameters: an ArrayList of Strings called wordList, and a String called targetWord This method should go through every element of wordList and remove every instance of targetWord from the ArrayList. Example: ArrayList<String> wordList = new ArrayList<String>(Arrays.asList("hi","hey","hi","yo")); removeAll(wordList,"hi"); wordList: ["hey","yo"] public static void main(String[] args) { Scanner in = new Scanner(System.in); int size = in.nextInt(); String target = in.next(); ArrayList<String> list = new ArrayList<>(); for(int i=0; i < size; i++) { list.add(in.next()); } System.out.println(removeAll(list, target)); } }maxLength Language/Type: Related Links: Java Set collections Set Write a method maxLength that accepts as a parameter a Set of strings, and that returns the length of the longest string in the set.

- 1- A new static method with one parameter which is a head node for a linked list of integers, the method should create a new linked list which is equivalent to the original list of integers but with all repetitions removed, the method's return value is a head reference for the new list. this is what I have but it's not removing repetitions. public static IntLinkedBag removeRepetition (IntLinkedBag b1) { IntNode next; IntNode head = null; LinkedList<Integer> s = new LinkedList<>(); IntNode new_list = new IntNode(0, null); IntNode now = head; IntNode prev = new_list; while (now!= null) { int x = now.data; if (s.contains(x)) { new_list = new_list.next; } else { s.add(x); new_list.next = new IntNode(x, now); new_list = new_list.next; } now = now.next; } return b1; } }…ISP-Java Write a program that gets a list of integers from the input value and outputs all integers less than or equal to the threshold value. The first input begins with an integer indicating the number of integers that the list (array) will hold. Based on the first input value, the user will then input integers into the list. Then, the last input integer will indicate the threshold. Output all integers less than or equal to that last threshold value. Assume that the list will always contain fewer than 20 integers. Ex: The following is an example of the input and output: Enter the number of integers that list will hold: 4 Enter integers for the list: 12 26 88 1999 Enter threshold integer: 28 Below are the integers that are <= to the threshold integer: 12 26Part2: LinkedList implementation 1.
