Multiple integers, representing the number of babies, are read from input and inserted into a linked list of TurtleNodes. Find the sum of all the integers in the linked list of TurtleNodes. Ex: If the input is 3 38 18 23, then the output is: 82 import java.util.Scanner; public class TurtleLinkedList { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); TurtleNode headTurtle = null; TurtleNode currTurtle = null; TurtleNode lastTurtle = null; int count; int inputValue; int i; int sum; count = scnr.nextInt(); headTurtle = new TurtleNode(count); lastTurtle = headTurtle; for (i = 0; i < count; ++i) { inputValue = scnr.nextInt(); currTurtle = new TurtleNode(inputValue); lastTurtle.insertAfter(currTurtle); lastTurtle = currTurtle; } /* Your code goes here */ System.out.println(sum); }} class TurtleNode { private int…

Code In Java Using Array or doubly Linklist instead of linklist COVID-19 has effect whole world. People are interested in knowing current situation of COVID-19. You are required to write JAVA program for storing information in a Array Following JAVA classes are provided. // Node class public class COVIDDetail { public String country; public int activecases; public COVIDDetail next; } // linked List class public class COVIDList { COVIDDetail start=null; } You are required to add following methods to COVIDList class void add(COVIDDetail n) this method receives a node as argument and adds it to given list. Nodes are arranged in descending order with respect to number of cases. Note that you are not required to sort the list in fact while adding first find its appropriate position and then add given node to that position. void updateCases(String country_name , int cases) this method receives two argument country name and cases (can have…
