- You are required to complete the LinkedList class. This class is used as a linked list that has many methods to perform operations on the linked list. To create a linked list, create an object of this class and use the addFirst or addLast or add(must be completed) to add nodes to this linked list. Your job is to complete the empty methods. For every method you have to complete, you are provided with a header, Do not modify those headers(method name, return type or parameters). You have to complete the body of the method. package chapter02; public class LinkedList { protected LLNode list; public LinkedList() { list = null; } public void addFirst(T info) { LLNode node = new LLNode(info); node.setLink(list); list = node; } public void addLast(T info) { LLNode curr = list; LLNode newNode = new LLNode(info); if(curr == null) { list = newNode; } else { while(curr.getLink() !=…Design and implement an insertSorted() method for the MyArrayList class. The method should receive a single object and insert it in its correct position. You can assume that the calling array is already in a sorted order. The calling array is therefore updated. Follow the three step method for designing the method. Develop the java code for the method. Create a test program to test the method thoroughly using the Integer wrapper class.Develop classes STint and STdouble for maintaining ordered symbol tables where keys are primitive int and double types, respectively. (Convert genericsto primitive types in the code of RedBlackBST.) Test your solution with a version ofSparseVector as a client.
- Import the ArrayList and List classes from the java.util package to create a list of phone numbers and also import the HashSet and Set classes from the java.util package to create a set of unique prefixes. Create a class called PhoneNumberPrefix with a main method that will contain the code to find the unique prefixes. Create a List called phoneNumbers and use the add method to add several phone numbers to the list. List<String> phoneNumbers = new ArrayList<>(); phoneNumbers.add("555-555-1234"); phoneNumbers.add("555-555-2345"); phoneNumbers.add("555-555-3456"); phoneNumbers.add("444-444-1234"); phoneNumbers.add("333-333-1234"); Create a Set called prefixes and use a for-each loop to iterate over the phoneNumbers list. For each phone number, we use the substring method to extract the first 7 characters, which represent the prefix, and add it to the prefixes set using the add method. Finally, use the println method to print the prefixes set, which will contain all of…TASK 7. Generic solution (Methods with Variable-Length Arguments). Review varargs, Implement the following code, test it with different input, make sure it runs without errors.Please use java. In this assignment, you will implement a class calledCustomIntegerArrayList. This class represents a fancy ArrayList that stores integers and supports additional operations not included in Java's built-in ArrayList methods. For example, the CustomIntegerArrayList class has a “splice” method which removes a specified number of elements from the CustomIntegerArrayList, starting at a given index. For a CustomIntegerArrayList that includes: 1, 2, 3, 4, and 5, calling splice(1, 2) will remove 2 items starting at index 1. This will remove 2 and 3 (the 2nd and 3rd items). The Cu stomIntegerArrayList class has 2 different (overloaded) constructors. (Remember, an overloaded constructor is a constructor that has the same name, but a different number, type, or sequence of parameters, as another constructor in the class.) Having 2 different constructors means you can create an instance of the CustomIntegerArrayList class in 2 different ways, depending on which constructor…
- Need help making a java file that combines both linearSearch and binarySearch •Both search methods must use the Comparable<T> interface and the compareTo() method.•Your program must be able to handle different data types, i.e., use generics.•For binarySearch, if you decide to use a midpoint computation formula that is different fromthe textbook, explain that formula briefly as a comment within your code. //code from textbook //linearSearch public static <T> boolean linearSearch(T[] data, int min, int max, T target) { int index = min; boolean found = false; while (!found && index <= max) { found = data [index].equals(target); index++; } return found; } //binarySearch public static <T extends Comparable<T>> boolean binarySearch(T[] data, int min, int max, T target) { boolean found = false; int midpoint = (min + max)/2; if (data[midpoint].compareTo(target)==0)…Explain briefly how generics make ArrayList more flexible.You are required to complete the LinkedList class. This class is used as a linked list that has many methods to perform operations on the linked list. To create a linked list, create an object of this class and use the addFirst or addLast or add (must be completed) to add nodes to this linked list(I created one linked list in TestLinkedList). I’ve already created the class for you and have some completed method in there, your job is to complete the empty methods.For every method you have to complete, you are provided with a header, Do not modify those headers( method name, return type or parameters). You have to complete the body of the method. public void add(T afterThis, T info) The parameter info will be the information the new node should contain, and the new node will be added after the node that contains the parameter afterThis as an information public void removeFirst() Removes the first node in the linked list. Hint: be aware of empty lists. public void removeLast() Removes…

You are asked to overload the method Insert. The method Insert will no longer take in a parameter position, this is because now Insert will place the element in the correct position such that the list is always sorted. Write the C++ code for the implementation of that Insert method.You are familiar with ArrayList and have used it in different capacities. The most prominent feature of ArrayList is that it expands automatically as elements are added to it. It can be traversed using a for loop, for each loop and iterator( which you have implemented in Lab 2).In this lab you are going to implement your own ArrayList and its functionalities.Task 1.1: Create a class Generic ArrayList with attributes.Task 1.2: Implement a constructor for your ArrayList class.Task 1.3: Implement add() method for adding elements to ArrayList. Remember, ArrayList adds elements dynamically. It doesn't depend on user defined size.Task 1.4: Implement remove() method for removing an element from a specific index. Remember, ArrayList stores elements in a consecutive sequence. If an element is removed from middle you have to re-adjust the elements in the correct sequence. Note: Break down your implementation by defining helper methods for different tasks, rather than implementing your logic in a…
