- The two classes you will create will implement the operations defined in the interface as shown in the UML class diagram above. In addition, BinarySearchArray will implement a static method testBinarySearchArray() that populates the lists, and lets the user interactively test the two classes by adding and removing elements. The parameter BinarySearch can represent either class and tells testBinarySearchArray which class to test. Steps to Implement: 1) To get started create a new project in IntelliJ called BinarySearch. Add a class to your project called BinarySearchArray. Then add another class BinarySearchArrayList and an interface called BinarySearch. The interface BinarySearch includes public method stubs as shown in the diagram. You are allowed to add BinarySearchArrayList to the same file as BinarySearch but don't add an access modifier to this class, or for easier reading, you can declare the classes in separate files with public access modifiers. Only the class…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…Java programming Create a file named StudentArrayList.java, within the file create a class named StudentArrayList. This class is meant to mimic the ArrayList data structure. It will hold an ordered list of items. This list should have a variable size, meaning an arbitrary number of items may be added to the list. Most importantly this class should implement the interface SimpleArrayList provided. Feel free to add as many other functions and methods as needed to your class to accomplish this task. In other words, the class StudentArrayList must implement the interface SimpleArrayList. You have to write the code for each of the functions specified in the SimpleArrayList interface. Make sure the class that implements SimpleArrayList is named "StudentArrayList" or else the test code will not compile. All of the documentation for the function guidelines may be found in the interface. This assignment can be a lot of programming if you do not follow the DRY (Don't Repeat Yourself)…
- Java Objects and Linked Data: Select all of the following statements that are true. The Java Class Library's class ArrayList implements the LinkedList interface. In Java, when one reference variable is assigned to another reference variable, both references then refer to the same object. In Java, the "equals"-method that any object inherits can be overwritten to compare objects field by field.code: public class PasswordGeneratorAndStorage {/*** Adds an application to the applications ArrayList. If index is -1, add application* to the end of applications. Else is index is within the size of applications, add* application at that index in applications. Otherwise, return. However, if applications * or application is null, return.* * @param applications* @param application* @param index*/public static void addApplication(ArrayList<String> applications, String application, int index) {// TODO: FILL IN BODY}/*** Generates a random password of length passwordLength and adds it to the end of* passwords if index is -1, or adds it to the index of passwords if index is within the* size of passwords (similar to how the addApplication adds an application). To generate* the random password, use rand to generate a random int within the size of characters. You* can then use this int to grab the char at that index in characters and concatenate that* to your String password variable.…EclipseIDE - 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.
- Generics enable you to specify the exact type that will be stored in a collection and give you the benefits of compile-time type checking—the compiler issues error messages if you use inappropriate types in your collections. Once you specify the type stored in a generic collection, any reference you retrieve from the collection will have that type. Instructions Write a program that inserts 25 random integers from 0 to 100 in order into Java’s LinkedList object (you must use Java’s LinkedList class to get any credit for this assignment). The program must: sort the elements, then calculate the sum of the elements, and calculate the floating-point average of the elements. For this assignments make sure that your screen shot(s) show your program running and that your runtime display shows your random list, sorted list, sum of the elements, and average of the elements. You only get credit for what you demonstrate. Below is a sample screen shot. Your output doesn’t have to look…What are the distinctions between an ArrayList and a Vector?Which collection class is best for data manipulation?Write a Python Code for the given constructor and conditions: Given Constructor: def __init__ (self, a) Pre-condition: Array cannot be empty. Post-condition: This is the default constructor of MyList class. This constructor creates a list from an array.
- addCourse: accepts an object of type Course as the first parameter and the idNum of the Student as the second parameter. The Course can be added only if the Student object with the specified idNum exists in the studentsList, Course does not exist in the coursesRegistered list for the Student, After adding the course, the number of credits, do not exceed 18. If the course is added successfully, return true, else return false.Create a file named StudentArrayList.java, within the file create a class named StudentArrayList. This class is meant to mimic the ArrayList data structure. It will hold an ordered list of items. This list should have a variable size, meaning an arbitrary number of items may be added to the list. Most importantly this class should implement the interface SimpleArrayList provided. Feel free to add as many other functions and methods as needed to your class to accomplish this task. In other words, the class StudentArrayList must implement the interface SimpleArrayList. You have to write the code for each of the functions specified in the SimpleArrayList interface. Make sure the class that implements SimpleArrayList is named "StudentArrayList" or else the test code will not compile. All of the documentation for the function guidelines may be found in the interface. This assignment can be a lot of programming if you do not follow the DRY (Don't Repeat Yourself) programming principle.…TaskDeclare and implement 5 classes: FloatArray, SortedArray,FrontArray, PositiveArray & NegativeArray.1- The FloatArray class stores a dynamic array of floats and itssize. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the end of the array.- Overloading for the insertion operator << to write the array to afile (ofstream)- Overloading for the extraction operator >> to read the arrayelements from the file (ifstream) and add them to the array.- A destructor to deallocate the array2- The SortedArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the right place in the arraysuch that the array remains sorted with every add. Don’t add tothe array then sort but rather add in the right place.3- The FrontArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the front of…
