PROBLEM STATEMENT: In this problem you will need to update a specific array element. You are provided two arguments one being the value for the update and then other being the index to where you will want to do the update. import java.util.ArrayList; public class UpdateSpecificElement{ public static ArrayList solution(ArrayList list, int val, int index){ // ↓↓↓↓ your code goes here ↓↓↓↓ return new ArrayList<>(); Can you help me with this question The language is Java

What transpires when a parameter for an array is sent in with either the ref or out keyword, and the results are observed?

Duplicate Set This function will receive a list of elements with duplicate elements. It should add all of the duplicate elements to a set and return the set containing the duplicate elements. A duplicate element is an element found more than one time in the specified list. The order of the set does not matter. Signature: public static HashSet<Object> duplicateSet(ArrayList<Object> list) Example: INPUT: [2, 4, 5, 3, 3, 5] OUTPUT: {5, 3}

PROBLEM STATEMENT: In this problem you will need to insert 5 at the frontof the provided ArrayList and return the list. import java.util.ArrayList;public class InsertElementArrayList{public static ArrayList<Integer> solution(ArrayList<Integer> list){// ↓↓↓↓ your code goes here ↓↓↓↓return new ArrayList<>(); Can you help me with this question  The Language is Java

6. the grade is under 20 which is outlier, remove it from the array list. 7. Print array list using System.out.println() 8. Use indexOf to print index of 80. 9. Use get function. 10. What is the difference between get and index of? 11. Print the values of the array list using Iterator class. 12.. Delete all the values of the array list using clear function. 13. Print all the values of the array after you execute clear using System.out.println(). what is the result of using clear function? 14. What is the shortcoming of using array List?

#Steps: Create a Main class. Declare an ArrayList in the main() method and store the given values in it. Create an array called output of the size of the ArrayList. Iterate through for-loop to get each element from the array List and load it into the array using the get() method of the list. Print the array to see the loaded elements.     import java.util.ArrayList; import java.util.List; public class Main {     public static void main(String[] args) {                 List<String> nameList = new ArrayList<String>();        nameList.add("Robert");        nameList.add("Samson");        nameList.add("Alex");        nameList.add("William");                    System.out.println("Elements of List: " + nameList);                 // Create an array of the same size as nameList Hint: use size() method                   // Fetch the elements from the nameList and insert into newly created array                  // Hint: Use get() method to fetch the elements from…
