- Arrays: create an array of a given type and populate its values. Use of for loop to traverse through an array to do the following : to print the elements one by one, to search the array for a given value. ArrayList: create an ArrayList containing elements of a given type . Use some of the common ArrayList methods to manipulate contents of the ArrayList. Write methods that will take an ArrayList as its parameter/argument ; and/or return an ArrayList reference variable as its return type. Searching for an object in an Array: Loop through the ArrayList to extract each object and to check if this object’s attribute has a given value. Explain how and why interfaces are used in Java Collection Framework. Explain the major differences between a Stack and a Queue. Be able to use stack and queue methods. What is meant by O(N) notation? Express the complexity of a given code using the O(N) notation.The purpose of this exercise is to create an Array List data structure that mimics the behavior of the Java Standard Library Version. Task Check List ONLY "for" loops should be used within the data structure class. The names of identifiers MUST match the names listed in the description below. data fields: The fields to declare have private accessibility. size : stores the number of occupied locations in internal array, and is of type int. data : is a reference variable for the internal array and is of type E[ ]. constant: Use to describe defaults. DEFAULT_CAPACITY is a constant that holds a default capacity of ten (10) for the underlying array, is of type int , public accessibility and modified to static. constructors: The overloaded constructors will initialize the data fields size and data. The default constructor calls the second constructor, generating an internal array with the specified DEFAULT_CAPACITY. public ArrayList() The second constructor generates an…Question Completion Status: Write a Java program that uses ArrayList and Iterator, It should input from user the names and ages of your few friends in a loop and add into ArrayList.

(Note that the array is created for you and does not need to be changed.) Until the user enters a sentinel value, allow the user four options: (1) to view the list in order from the first to last position in the stored array (2) to view the list in order from the last to first position (3) to choose a specific position to view (4) to quit the application. -------- using System; using static System.Console; class ArrayDemo { static void Main() { int[] nums = {7, 6, 3, 2, 10, 8, 4, 5, 9, 1}; // Write your main here } }4.
