Your task is to: Implement the LinkedList interface ( fill out the implementation shell). Put your implementation through its paces by exercising each of the methods in the test harness. Create a client ( a class with a main ) ‘StagBusClient’ which builds a bus route by performing the following operations on your linked list: - Create (insert) 4 stations - List the stations - Check if a station is in the list (print result). Check for a station that exists, and one that doesn’t - Remove a station. List the stations - Add a station before another station. List the stations - Add a station after another station. Print the stations LinkedList.java package linkedList; public interface LinkedList { public Boolean isItemInList(String thisItem); // true if it is, false if not public Boolean addItem(String thisItem); // true if added, false if it was already there, or an error public Integer itemCount(); public void listItems(); public Boolean deleteItem(String thisItem); // true if deleted,…
Write a method called CompareAndChangeList to be included in an application class called ListApplication that accepts two parameters list1 and list2 of type SingleLinkedList of integer values, and a third parameter Item of type int. If list1 and list2 are of different sizes, the method returns false, otherwise, the method replaces any element in list2 with a value equal to the last element in list1, if the summation of the element in list 1 and the corresponding element in list2 is equal to item. Assume list1 and list2 are not empty. If at least one replacement happened, the method returns true, otherwise, it returns false. Note: Write this method by calling methods of the class SingleLinkedList. Method head: public static boolean CompareAndChangeList (SingleLinkedList<Integer> list1, SingleLinkedList<Integer> list2, int item) Example: Before Method call: item = 35 list1: 23 26 30 20 17 list2: 10 9 25 15…
Suppose we want to extend the PositionalList ADT with a method, indexOf(p), that returns the current index of the element stored at position p. Write this method using only other methods of the PositionalList interface (not details of our LinkedPositionalList implementation). Write the necessary code to test the method. Hint: Count the steps while traversing the list until encountering position p public interface PositionalList<E> extends Iterable<E> { int size(); boolean isEmpty(); Position<E> first(); Position<E> last(); Position<E> before(Position<E> p) throws IllegalArgumentException; Position<E> after(Position<E> p) throws IllegalArgumentException; Position<E> addFirst(E e); Position<E> addLast(E e); Position<E> addBefore(Position<E> p, E e) throws IllegalArgumentException; Position<E> addAfter(Position<E> p, E e) throws IllegalArgumentException; E set(Position<E> p, E e) throws…
Given the MileageTrackerNode class, complete main() in the MileageTrackerLinkedList class to insert nodes into a linked list (using the insertAfter() method). The first user-input value is the number of nodes in the linked list. Use the printNodeData() method to print the entire linked list. DO NOT print the dummy head node. Ex. If the input is: 3 2.2 7/2/18 3.2 7/7/18 4.5 7/16/18 the output is: 2.2, 7/2/18 3.2, 7/7/18 4.5, 7/16/18 public class MileageTrackerNode { private double miles; // Node data private String date; // Node data private MileageTrackerNode nextNodeRef; // Reference to the next node public MileageTrackerNode() { miles = 0.0; date = ""; nextNodeRef = null; } // Constructor public MileageTrackerNode(double milesInit, String dateInit) { this.miles =…
Using eclipse, write a Console Java program that inserts 25 random integers in the range of 0 to 100 into a Linked List. (Use SecureRandom class from java.security package.SecureRandom rand = new SecureRandom(); - creates the random number objectrand.nextInt(100) - generates random integers in the 0 to 100 range)Using a ListItreator output the contents of the LinkedList in the original order. Using a ListItreator output the contents of the LinkedList in the reverse order.
Implement a lastIndex method for the LinkedIntList class you worked on for HW4. This method takes an int argument and returns the largest index such that the int argument appears at that index in the list. If the int argument does not appear in the list, then -1 is returned. For example if the list example contained the numbers [4, -1, 2, 7, -1, 3] in that order, then example.lastIndex(-1) should return 4 and example.lastIndex(5) should return -1. In the text area below, write the definition of the lastIndex method. (In other words, write the code that should replace the //TODO comment.) Your code cannot call any methods. public class LinkedIntList { private class Node { private int item; private Node next; public Node() {} public Node(int number, Node nextNode) { item = number; next = nextNode; } } private Node first; // first node of the list public LinkedIntList() { first = null;…
Write a method called removeLeastNumber in the class WLinkedList (a class for doubly linked list as discussed in the lectures). The method will search for the smallest integer in the double linked list and removes the node that contains that value. Assume that the list must contain at least two nodes. Assume further that the smallest value never be in the first node. Do not use Iterators and you are not allowed to call any of the KWLinkedList class methods. Method heading: public void removeLeastValue() Example: list (before method call): 7 10 2 3 5 3 9 list (after method call): 7 10 3 5 3 9
One use of a hash table is to implement a set data type. You will implement the methods addElement, find, toString, resize, and the MySetIterator inner class in the class MySet. MySet uses a separate chaining hash table to implement a set of integers. To get started, import the starter file, MySet.java into the hashset package you create in a new Java Project. Please do not change any of the method signatures in either class. Implement the methods described below. You are free to test your code however you prefer. Below is method Signature class: package hashset; import java.util.Iterator; public class MySet { // implements a set using a separate chaining hash table private class Node { private Integer element; private Node next; private Node(Integer e, Node n) { element = e; next = n; } } private Node table[]; //an array of linked list private int tableSize; //current number of lists in the table private int…

The table size should remain prime. private boolean find(Integer e)This method returns true if the integer e is in the set and false otherwise. private void addElement(Integer e)If e is not in the set, add e to…

For this Problem, you will implement a brute force solution to the maximum-subarray problem that runs in O(n2) time (i.e., your solutions should have two nested loops). You will implement this solution for an array of ints and a simple LinkedList of ints. To get started, import the two starter files into the subarray package you created in a new Java Project. Please do not change any of the method signatures or any code in the provided LinkedList class. Implement the two methods described below. public LinkedList findMaximumSubList(LinkedList nums) This method should return a new LinkedList that represents the maximum sublist of the given LinkedList, nums. For example, the maximum sublist of 13->-3->-25->-20->-3->-16->-23->18->20->-7->12->-5->-22->15->-4->7 is 18->20->-7->12 public int[] findMaximumSubArray(int[] nums) This method should return a new int[] that represents the maximum subarray of the given int[], nums. For example,…
