Question

please explain how to code using java

-. Implement the ListNode and LinkedIntList as we did in class (you can add other methods if needed). You can reference the coxle in powerpoint slides of LinkedList and your textbook. 2. Implement a LinkedIntList class with the following public operations. a. add(int value) - Adds the given value to the end of the list b.get(int index) - Retums value in list at given index. C.add( int index, int value) - Inserts the given value at the given index. d.size()- Get the size of the current list. e. remove()- Removes and retums the first value. Throws a NoSuchElementException on empty list. f. remove(int index) – Removes value at given index g.toString() - Convert the list into a String, node by node. Such as (14.23.3.22.8] 3. After implementing the ListNode. LinkedIntList classes you will test them. To test those classes you will create a Lab9 package. 4. In the Lab9 class you will create a static void main() method. In this main method you will do the following: a. Create a intList of LinkedIntList type. b. Add the first 30 perfect square numbers (1,4,9, ... , 900) into the intList one by one using add and append alternatively. c. Print the intList. d. Print the current size of intList. e. Remove 25, 36, 64, 100, and 400 from the intList. f. Print the intList. g. Print the current size of intList. h. Add 0 as the first element in your intList. i. Return the values from index 0 to index 5. j. Print the intList.

Instructions

1. Save the program as Linked_List.java
2. Open cmd
3. Set the path of your java programeg. For eg: set path="C:\Program Files\Java\jdk-14.0.1\bin";
4. Complie using, javac Linked_List.java
5. Run using, java Linked_List

Java Program:

System.out.println("The Element Returned by Index 0 is "+list.get(4));
System.out.println();
System.out.println("The Element Returned by Index 0 is "+list.get(5));
System.out.println();
System.out.println("The Final Updated Linked List is as follows...");
System.out.println(list);//Print the Updated Linked List
