java Part I Create an interface for a Book object. Provide at least 3 function. Part II Create a type of Book class. Implement the methods introduced in the interface. with tostring and getters and setters
Step by step
Solved in 4 steps with 6 images
- Java Programming Create your own class that illustrates the use of encapsulation. Make sure to include at least one setter and one getter for the classJava- Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).
- CS Java Program (NEED HELP WITH THE ACTUAL CODING PART): For this project, you will create an application for a zoo. You will need to create a class that implements the iAnimal interface (provided below), and use one other class for an additional animal that implements the iAnimal interface as well (provided below). Modify the animal classes that you will use for this project so they implement Java’s comparable or comparator interface. You will also need a Main Class that will provide a user interface for this application. This can be a console-based interface. Tasks can be performed in one or more methods as needed. The Main Class should have one or more methods that handle these tasks: Create a new instance (object) of each of the animal classes and pass the user input as arguments to the object's mutator methods to set the private instance data for the appropriate animal class. Create an ArrayList of type iAnimal and add the new instance created in task 1 to the ArrayList. Before…CODE IN JAVA Please look at the attached image for the information about the format the code should be in The code should be in two different .java files one with getFirstName, getLastName and getZipCode; the other file would be containing the main method Design and implement an application that reads a sequence of up to 25 pairs of names and postal (zip) codes for individuals. Store the data in an object of a class called “NameAndZip”, designed to store a first name (String), last name (String), and a postal code (int). Create a driver class called “NameAndZipList”. Assume that each line of input will contain two strings followed by an integer value. You will then create an object for each line read in and store that object in an array of NameAndZip objects. After the Names and Codes have been entered, print the list in an appropriate format to the screen using the toString method in the NameAndZip class. To test the program enter 3 names and codes.T/F1. Interface classes cannot be expanded, but implementation classes may.
- Please do it in JavaScript or C# 1) Design and implement the class structure for a drawing application. A drawing is made up of a canvas that contains a collection of three different shapes: circles, lines, and boxes. Each shape can be drawn by calling a Draw() method for that shape. The canvas class should also have a draw method that draws all of the shapes it contains. You don’t have to actually draw anything on a screen; you can simulate drawing by writing a message to the console.For example, the code snippet: canvas.Draw();Drawing a circle at...Drawing a line at...etc. (For each shape on the canvas) 2)(Bonus) Consider re-writing the above answer (#1) differently where the canvas does not contain the shapes, but is able to draw any of the three shapes passed to it. Re-design canvas.Draw() if you need to. Your main() program should ask for user input on what shape to draw. Ask once, draw, then exit.could produce something like the following output to the console:python programming Implement a constructor for the Person class Implement a constructor for the Student class Create a student with name; Albert Einstein, ramq: 14031879-1235, address: 112 Mercer Street, Princeton, courses: (1)Physics & (2)Relativity where the grades were b and a respectively and with enrollment date: 1895 partial solution attached in the imagePython:Please read the following. The Game class The Game class brings together an instance of the GameBoard class, a list of Player objects who are playing the game, and an integer variable “n” indicating how many tokens must be aligned to win (as in the name “Connect N”). The game class has a constructor and two additional methods. The most complicated of these, play, is provided for you and should not be modified. However, you must implement the constructor and the add_player method. __init__(self,n,height,width) The Game constructor needs to initialize three instance variables. The first, self.n, simply holds the integer value “n” provided as a parameter. The second, self.board, should be a new instance of the GameBoard class (described below), built using the provided height and width as dimensions. The third, self.players, should be an initially empty list. add_player(self,name,symbol) The add_player method is provided a name string and a symbol string. These two values should be…
- Implement the following hierarchy using C++ classes. 1. Shape: This should be an interface class that supports area() and display() functions. 2. Circle and Rectangle: Implement the area and display functions of Shape. 3. Quadrilateral: This class should be an abstract class. It may contain member variables for length and height. 4. Trapezoid: Should inherit length, height from Quadrilateral, and add 'side', represents the side parallel to 'length'. 5. Create appropriate .h/.cpp files with constructors and destructors (wherever needed). which 6-T/F1. Interface classes cannot be extended but classes that implement interfaces can be extended.Python programming Implement a constructor for the Person class Implement a constructor for the Student class Create a student with name; Albert Einstein, ramq: 14031879-1235, address: 112 Mercer Street, Princeton, courses: (1)Physics & (2)Relativity where the grades were b and a respectively and with enrollment date: 1895
