A student record system uses an ArrayList object called studrecs tomaintain a collection of student details where each student is anobject defined by the Student class. The student class has accessormethods getName() and getRegNo()Write a for-each loop that iterates through the studrecs collectionwriting out each student’s name and registration number.

How do I match the output?

Given main() and an IntNode class, complete the IntList class (a linked list of IntNodes) by writing the insertInDescendingOrder() method to insert new IntNodes into the IntList in descending order. Ex. If the input is: 3 4 2 5 1 6 7 9 8 -1 the output is: 9 8 7 6 5 4 3 2 1   import java.util.Scanner; public class SortedList { public static void main (String[] args) {Scanner scnr = new Scanner(System.in);IntList intList = new IntList();IntNode curNode;int num; num = scnr.nextInt(); while (num != -1) {// Insert into linked list in descending order curNode = new IntNode(num);intList.insertInDescendingOrder(curNode);num = scnr.nextInt();}intList.printIntList();}}

Given main() and an IntNode class, complete the IntList class (a linked list of IntNodes) by writing the insertInAscendingOrder() method that inserts a new IntNode into the IntList in ascending order. Ex.
