You are familiar with ArrayList and have used it in different capacities. The most prominent feature of ArrayList is that it expands automatically as elements are added to it. It can be traversed using a for loop, for each loop and iterator( which you have implemented in Lab 2).In this lab you are going to implement your own ArrayList and its functionalities.Task 1.1: Create a class Generic ArrayList with attributes.Task 1.2: Implement a constructor for your ArrayList class.Task 1.3: Implement add() method for adding elements to ArrayList. Remember, ArrayList adds elements dynamically. It doesn't depend on user defined size.Task 1.4: Implement remove() method for removing an element from a specific index. Remember, ArrayList stores elements in a consecutive sequence. If an element is removed from middle you have to re-adjust the elements in the correct sequence. Note: Break down your implementation by defining helper methods for different tasks, rather than implementing your logic in a…

using java, finish the two arrayList methods below: public int indexOf(Object o) { } public E remove(int index) { } and then create a class to test the ArrayList methods
java Write a program to do the following: Create an ArrayList of Student. Add 7 elements to the ArrayList. Use for each loop to print all the elements of an ArrayList. Remove an element from an ArrayList using the index number. Remove the element from an ArrayList using the content (element name).
Java Programming assigment For your program: Create a data class named Automobile that implements the Comparable interface. Give the class data fields for make, model, year, and price. Then add a constructor, all getters, a toString method that shows all attribute values, and implement Comparable by using the year as the criterion for comparing instances. Write a program named TestAutos that creates an ArrayList of five or six Automobiles. Use a for loop to display the elements in the ArrayList. Sort the Arraylist of autos by year with Collections.sort(). Finally, use a foreach loop to display the ArrayList sorted by year.
this is the template to be user. Add the code here according to the question in image. in java language. public class MergeSort { ArrayList getInput(ArrayList<Integer> al) { // } void getOutput(ArrayList<Integer> al) { // } void merge(ArrayList<Integer> al, int beg, int mid, int end) { // } void sort(ArrayList<Integer> al, int beg, int end) { // } public static void main(String[] args) { // TODO Auto-generated method stub } }
Design and implement an insertSorted() method for the MyArrayList class. The method should receive a single object and insert it in its correct position. You can assume that the calling array is already in a sorted order. The calling array is therefore updated. Follow the three step method for designing the method. Develop the java code for the method. Create a test program to test the method thoroughly using the Integer wrapper class.
Exercise #2 Implement an instance method belonging to the IntArrayBag class that takes two input parameters, oldVal and newVal. The method replaces each oldVal element in the array with newVal. Make sure to include the method header.
Use the ArrayList class Add and remove objects from an ArrayList Protect from index errors when removing Practice with input loop Details: This homework is for you to get practice adding and removing objects from an ArrayList. The Voter class was used to create instances of Voters which held their name and a voter identification number as instance variables, and the number of instances created as a static variable. This was the class diagram: The constructor takes a string, passed to the parameter n, which is the name of the voter and which should be assigned to the name instance variable. Every time a new voter is created, the static variable nVoters should be incremented. Also, every time a new voter is created, a new voterID should be constructed by concatenating the string “HI” with the value of nVoters and the length of the name. For example, if the second voter is named “Clark Kent”, then the voterID should be “HI210” because 2 is the value of nVoters and 10 is the number…
Implement the following method where: 1. String s is a given string 2. myArray is an array list that contains strings 3. The method findExactString will take the string s and the arraylist myArray and return an arraylist that contains the indices of all strings in myArray that matches the string s. If the reference to the string is null and the reference to the string inside the array is also null, string s is considered to be a equal to the string in arraylist. public static ArrayList findExactString(String s, Arraylist myArray) { return null;
