Question 5 Assume that the following method is in a class called DLL (not same as KWLinkedList). What does this method do? public void method_LI( ) { KWLinkedList<Integer> list = new KWLinkedList<Integer>( ); list.add(2); list.add(-1); list.add(0); list.add(1); list.add(0); ListIterator<integer> iter = list.listIterator(); while(iter.hasNext()) { if (iter.next() == 0) iter.remove(); } if( iter.hasPrevious() ) System.out.println("END"); else while(iter.hasNext()) System.out.print(iter.next() + " "); } Removes the nodes having 0 as its data and prints END. Removes the nodes having 0 as its data and prints 2 -1 1 Removes the nodes having 0 as its data and prints 1 -1 2 Prints 2 -1 0 1 0 without removing anything.
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; } }…
In Java, Create Movie class, which has private fields for title, director, rating. It has a constructor to initialize these fields and a toString method for printing movie details. There is also a getRating method to retrieve the movie rating. Create Rating Comparator class which implements the Comparator interface for comparing movies based on their ratings. Create DemoMovies Class. Initialize necessary data structures like LinkedList, TreeMap for rating as key and Movie from Movie class as value, TreeSet, and ProtiyQueue. Use a loop to take user input for movie detailsuntil the user enters 'WWW' as the movie title.Inside the loop, for each movie, create a Movie object, add it to various data structures that is title, director and rating based on the constructor. Add the Movie object to the LinkedList. Add the rating and the object to the TreeMap.Add the rating to the TreeSet.Add the Movie object to the Priority Queue.Display the entered movies. Sort and display Movies by rate by…

1. Show the ListStackADT<T> interface 2. Create a ListStackDataStrucClass<T> with the following methods: defaultconstructor, overloaded constructor, copy constructor, getTop, setTop,isEmpty, ifEmpty (if empty throw the exception), push, peek, pop, toString. 3. Create a private inner class of ListStack<T> called StackNode<T> with thefollowing methods: default constructor, overloaded constructor, copyconstructor, getValue, getNext, setValue, setNext 4. Create a BaseConverter class (non-generic) with the following methods: defaultconstructor, inputPrompt, convert [converts a BaseNumber to a convertedString], convertAll [instantiate a String object] , toString, processAndPrint 5. Create a private inner class BaseNumber. The inner class has the following methods: default constructor, overloaded constructor, getNumber, getBase,setNumber, setBase. [Make your private instance variables in the inner classLong type]. 6. Create a BaseConverterDemo class that only…
Write a method called swapItems to be considered within the SingleLinkedList class that takes two parameters, index1 and index2 of type integer. The method swaps the data of the nodes at the given indexes. If any of the parameters indexes is invalid throw IndexOutOfBoundsException. Do not call any method of class SingleLinkedList in your method. Method heading: public void swapItems(int index1, int index2) Example: index1 = 2 index2 = 4 Before method call: list: 5 10 12 9 11 7 After method call: list: 5 10 11 9 12 7

Assume you have a method (shown below) inside the single linked list class, what does this method do? private E remove () { Node temp = head; if (head != nulI) { head = head.next; size--; return temp.data } else return null; } (A Remove the first node in the list and return the data of the deleted node or null if the list is empty. Remove the node after the node referenced by temp and return the data of the deleted node or null if the list is (в empty. Remove all the nodes of the linked list and return the data of the last node deleted or null if the list is empty.

java program : Given the following method to be considered within the SingleLinkedList class, what does this method do? public void Undefined() { Node<E> ptr = head; if (ptr == null || ptr.next == null) return false; E item1 = ptr.data; while (ptr.next != null) ptr = ptr.next; E item2 = ptr.data; if (item1.equals(item2)) { head = head.next; size--; } } If the first element of the list is equal to the second element of the list, then the method deletes the second node. If the first element of the list is equal to the last element of the list, then the method deletes the first node. If the first element of the list is equal to the second element of the list, then the method deletes the first node. If the first element of the list is equal to the last element of the list, then the method deletes the last node.
