Explanation of Solution
Method to add all the elements from one collection to another collection:
Addall(collection C) is the method used to add all the elements from one collection to another. The elements may be added individually.
Sample Program:
//Java program to illustrate addAll(Collection c)
import java.util.ArrayList;
public class Sample
{
public static void main(String args[])
{
// Creating array list1
ArrayList<Integer> collect1 = new ArrayList<Integer>(5);
// Adding elements to the list1
collect1.add(12);
collect1.add(20);
collect1.add(45);
// prints all the elements available in array //list1
System.out.println("Printing list1:");
for (Integer number : collect1)
System...

- please for lists are not allowed for this question. please use out own code and a picture, can you also put comments to uderstand better... thank youarrow_forwardWrite assignments to the library, cs101, and track variables (which you defined in the previous three exercises) to create the appropriate ArrayList objects. Write them once using diamond notation and once without diamond notation, specifying the full type.arrow_forwardWhich accesses the number of elements in groceryList?

- How can you count duplicate elements in a given list?arrow_forwardCreate a data type that allows you to insert, remove the maximum, and delete the minimum (all in logarithmic time), as well as locate the maximum and find the minimum (both in constant time). Use two piles as a hint.arrow_forwardI need to write changeArrayLength(int m) – void method; I already have the code (attached below) but it needs debugging... This method creates a new student table for this course; this new table has the given length m; the method moves all registered students to this table. This method creates a new array of SLinkedList<Student>, moves all the registered students into these linked lists, and changes this course’s studentTable field so it references this new table instead. Each student in the current table will be moved to the new table. This will require in most cases that the student is moved to a different array slot index. The slot index for the SLinkedList<Student> that they are moved to is id % m, where m is the new length of the array (the parameter of the method). The motivation for increasing the capacity of the array is that it keeps the average lengths of the linkedlists below 1, which tends to mean a fast traversal of each linked list. public class Course {…arrow_forward
