You must DESIGN, ANALYSE AND CODE any method for the GENERIC MyLinkedList class that will manipulate the linked list. You can decide yourself what it should be following the specification below: 1. Purpose: The method must make logical sense - it should be of some purpose to somebody. You should describe in the text who will use the method for which purpose. 2. Clearly explain the problem. Then clearly explain how your method will solve it. 3.

- How can the effectiveness of an ArrayList be evaluated?arrow_forwardYou 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() !=…arrow_forwardplease follow instructions correctly.

- How can you evaluate the state of an ArrayList to assess how effectively it is functioning?arrow_forwardImport 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…arrow_forwardDesign 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.arrow_forward
