Include a main method and test all your methods with appropriate examples. a. Write a method called scaleByK() that takes an ArrayList of integers as a parameter and replaces every integer of value K with K copies of itself. For example, if the list stores the values (4, 1 , 2, 0 ,3) before the method is called, it should store the values (4, 4, 4, 4, 1, 2, 2, 3, 3, 3) after the method finishes executing.

need Urgent Requirement: There will one question related to ArrayList class similar to the following question. The following driver has created a an ArrayList of Point objects. write a method that moves all the points with the value of x greater than its value of y to the end of the list. .
Define a class called Book. This class should store attributes such as the title, ISBN number, author, edition, publisher, and year of publication. Provide get/set methods in this class to access these attributes. Define a class called Bookshelf, which contains the main method. This class should create a few book objects with distinct names and store them in an ArrayList. This class should then list the names of all books in the ArrayList. Enhance the program by providing a sort function, which will sort the books in ascending order of their year of publication. Create a few more Bookobjects with the same names but with different edition numbers, ISBNs, and years of publication. Add these new Book objects to the ArrayList, and display the book list sorted by book name; for duplicate books of the same name, sort the list by year of publication. (Hint: You will need to define a comparator class that takes two Book objects as parameters of the compareTo This method should do a two-step…
Please use java only and public int method. Show the steps with the pictures also. In this assignment, you will implement a class calledArrayAndArrayList. This class includes some interesting methods for working with Arrays and ArrayLists. For example, the ArrayAndArrayList class has a “findMax” method which finds and returns the max number in a given array. For a defined array: int[] array = {1, 3, 5, 7, 9}, calling findMax(array) will return 9. There are 4 methods that need to be implemented in the A rrayAndArrayList class: ● howMany(int[] array, int element) - Counts the number of occurrences of the given element in the given array. ● findMax(int[] array) - Finds the max number in the given array. ● maxArray(int[] array) - Keeps track of every occurrence of the max number in the given array. ● swapZero(int[] array) - Puts all of the zeros in the given array, at the end of the given array. Each method has been defined for you, but without the code. See the javadoc for each…
Write Java code for the following: Create an Arraylist that can hold Integer objects. Check and display whether the Arraylist is empty or not. Add an element 50 into the Arraylist. Add another element 60 in the position of 0 in the Arraylist. Replace the element to 70 in index 1.

Create a class called MyArrayList and implement the methods below, in addition to a main method to testyour code. Focus on the special cases.1. Write a method intersect that accepts two sorted array lists of integers as parameters and returns anew list that contains only the elements that are found in both lists. Example: if lists named list1 andlist2 initially store:[1, 4, 8, 9, 11, 15, 17, 28, 41, 59][4, 7, 11, 17, 19, 20, 23, 28, 37, 59, 81]Then the call of intersect(list1, list2) returns the list:[4, 11, 17, 28, 59]Write a main method to test your code. Focus on the special cases2. Write a method reverse that reverses the order of the elements in an ArrayList of strings.3. Write a method capitalizePlurals that accepts an ArrayList of strings and replaces every word endingwith an "s" with its uppercased version.4. Write a method removePlurals that accepts an ArrayList of strings and removes every word in the listending with an "s", case-insensitively.5. Write a method called…
Nedd help in this. Must be in java. make the code unique and no plagerism. write a program that prints out the lists in main after the following methods are called. removeOddLength: Takes an ArrayList of strings as a parameter and removes all of the strings that have an odd length (number of characters), from the list. Return the ArrayList to main and print. swapPairs: Takes an ArrayList and switches the order of values of strings in a pairwise fashion. Your method should switch the order of the first two values, then the next two, then the next two and so on. If the number of values in the list is odd, the method should not move the final element. For example, if the list stores [“madam”, “I”, “am”, “your”, “adam”] your method should change this lists content to [“I”, “madam”, “your”, “am”, “adam”] Return the ArrayList to main and print. intersect: Accepts two sorted ArrayList of integers as parameters and returns one containing only the elements that are found in both. For…
Add a getUnsold method to the Auction class with the -following header: public ArrayList getUnsold() This method should iterate over the lots field, storing unsold lots in a new ArrayList local variable. What you are looking for is Lot objects whose highestBid field is null. At the end of the method, return the list of unsold lots.
