- The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.Here you can find the java code and photo of challenge: import java.io.*;import java.math.*;import java.security.*;import java.text.*;import java.util.*;import java.util.concurrent.*;import java.util.function.*;import java.util.regex.*;import java.util.stream.*; public class Solution { public static class DirectedGraph {/* Adjacency List representation of the given graph */private Map<Integer, List<Integer>> adjList = new HashMap<Integer, List<Integer>>(); public String toString() {StringBuffer s = new StringBuffer();for (Integer v : adjList.keySet())s.append("\n " + v + " -> " + adjList.get(v));return s.toString();} public void add(Integer vertex) {if (adjList.containsKey(vertex))return;adjList.put(vertex, new ArrayList<Integer>());} public void add(Integer source, Integer dest) {add(source);add(dest);adjList.get(source).add(dest);} /* Indegree of each vertex as a Map<Vertex, IndegreeValue> */public Map<Integer, Integer> inDegree()…Suppose you are given two circularly linked lists, L and M. Develop javaapplication for telling if L and M store the same sequence of elements (butperhaps with different starting points).
- Programming in Java. What would the difference be in the node classes for a singly linked list, doubly linked list, and a circular linked list? I attached the node classes I have for single and double, but I feel like I do not change enough? Also, I use identical classes for singular and circular node which does not feel right. Any help would be appreciated.PLEASE SOLVE IN JAVA.

- Apply the methods in the ListIterator interface to write a Java program in NetBeans that creates a LinkedList of four elements of type string, namely: Java, C#, PHP and Python. The program should then print out the elements initially in the original order, and then afterwards in reverse order using the ListIterator methods. In this case, the following is the expected output:How do I solve this 3 step problem dealing with fitness and calorie tracking in java? thnks and please dont use arrays or lists to solve it :<)Using the picture, use Java to design and implement the class PascalTriangle that will generate a Pascal Triangle from a given number of rows. Represent each row in a triangle as a list and the entire triangle as a list of these lists, implement the class ArrayList for these lists.
