Consider the IntArrayBag collection class that we discussed in class, Draw the data array after executing the following code and show the values that are stored in each cell of the array. Show the array four times at the points labelled A, B, C, and D IntArrayBag bag1 = new IntArrayBag(5); bag1.add(10); bag1.add(5); bag1.add(20); bag1.add(13); //Point A bag1.remove(5); //Point B bag1.add(8); bag1.remove(10); //Point C bag1.add(30); //Point D Exercise 4: search method

java coding Write a method that will search an integer array for a number and return the count of how many times the number is in the array. The array is not sorted. Any inputs that the method needs must be part of the parameter list, not input from the user or a file or taken from the instance data
Main difference between an array and an ArrayList is that an ArrayList can store more data types an ArrayList can store more elements an ArrayList executes faster for retrieval and insertion an ArrayList takes care of the memory management automatically an ArrayList uses positions and an array uses indices
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…

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.
19. A two-dimensional array is frequently called a matrix and such a matrix is usually displayed in a row X col format. Write a method, which displays a 3 X 4 matrix to the monitor, in a format like: sample data: 10 11 12 13 14 15 16 17 18 19 20 21 Complete method displayMatrix below. // precondition: // postcondition: 11 mat is a non-empty 2D array of int values. displayMatrix displays the elements of 2D array mat in Row X Col format. public static void displayMatrix(int[][] mat)
1. Declare an array to save 4 Dog objects. The Dog class is provided below. Look into the Dog class and find what attributes are needed for a dog object. Then initialize five dogs with the following information: Lily, 5 years old Jacob, 2 years old Sugar, 8 years old Bush, 3 years old 2. Print out every dog using a for loop (use either regular for loop or for-each loop, your choice). But you may find when you print out, the name and age are not displayed. Why? 3. Fix this problem by implementing the toString method in the Dog class. Dog Class: public class Dog { private String name; private int age; public Dog(String name, int age) { this.name = name; this.age = age; } public void setName(String name) { this.name = name; } }
Determine if the following statement are true or false Screen shot shows the text's arraycollection When comparing two objects using the == operator, what is actually compared is the contents of the objects. The equals method of the Object class returns true only if the two objects being compared have identical attributes. A collection allows retrieval of information based on the size of the information. With the text's array-based collection implementation, the set of stored elements is scattered about the array.
Java Given a 2 dimensional array, write a method to return the average of each row. The result must be returned as a one dimensional array. The array may be ragged. For example: int[][] my2DArray = { {2,5,5}, {2,6,8,4}, {6,5,2,3} } The result should be: int[] myArrayAverage = { 4, //Average of {2,5,5} 5, //Average of {2,6,8,4} 4 //Average of {6,5,2,3} } Note: You only need to write down the code inside the myMethod() code block public class CST1201Test3 { public static void main(String[] args) { int[][] my2DArray = { {2,5,5}, {2,6,8,4}, {6,5,2,3} }; int[] myArrayAverage = myMethod(my2DArray)); } static int[] myMethod(int[][] numbers) { // your answer } }
Class Gradebook2D The class Gradebook2D will produce the same output of the class Gradebook1D, but the implementation will be slightly different. You will need to use only two arrays:  One array of type int to store all the ID's (just like the previous class).  One two‐dimensional array of type double to store all the scores for all quizzes. Example: Assume there are 10 students in the class, then the id array will have 10 indices. 0 1 2 3 4 5 6 7 8 9 132 451 854 523 153 588 351 856 142 445 Each quiz array will store in the index that corresponds to the student the score for the quiz. 0 1 2 3 4 5 6 7 8 9 100.0 90.0 85.0 92.0 75.0 93.0 98.0 100.0 95.0 87.0 90.0 87.0 92.0 95.0 78.0 84.0 88.0 96.0 100.0 95.0 100.0 98.0 85.0 98.0 87.0 89.0 92.0 88.0 92.0 97.0 Student with ID 153, at index 4, has taken all three quizzes with scores 75.0 (quiz 1), 78.0 (quiz 2) and 87.0 (quiz 3). Note: The two dimensional array can be represented also with the rows being the students and the columns…
