Which of these statements IS NOT true regarding design by contract. Question options: Creating and implementing an interface is an example of implicit design by contract. Explicit design by contract makes specifications part of the compiled code for a program. Creating and building from an abstract class is an example of explicit design by contract. When we code to an interface, we create a set of methods to be used to interact with a class; these methods establish a contract for how the design should work. Option B is not the correct answer.
Please explain each and the output and make a program on: Java program with the following specifications The class names to... Java program with the following specifications The class names to be created are the following: Client (the main class that contains the main method and the implementation of the main menu) Credit (the class where attributes and methods are defined) *Note that the object to be instantiated in the main method is an object array. For example: Credit [ ] cb = new Credit [100]; New Credit Account Input the name of the client. Input the annual income and assign the credit limit as follows: Credit Limit 200,000 and above but not greater than 300,000 30,000 300,000 and above but not greater than 500,000 50,000 500,000 and above 100,00 Generate and display a random four-digit credit account number. Display also the credit limit. The credit limit is the maximum amount of…
Do the following in Java and provided source code with screenshots of correct output to show it works! (New Solution without AI) 1. Create an interface Vehicle that contains three void, abstract methods named Start, Stop and Change Speed. 2 .Create an Airplane class (not abstract) that uses the Vehicle interface in Q1. The code for all methods should print simple messages to the screen using System.out.println(). Add an integer speed variable that is changed using the Change Speed method. ChangeSpeed adds 5 to the speed each time it is called. Create a default constructor that sets the initial speed to 0. Don't create other constructors or any setter/getter methods. 3. Create an abstract class Car that also uses the Vehicle interface in Q1 and has three variables, Year, Make, and Speed. Include the following: One constructor that accepts the car's year and make as arguments. The constructor should also assign 0 to the speed variable. Do not create other constructors. Create a void…
Question Two In the first task, it is necessary to model the classes and interfaces that are necessary to describe the simplified model of the music industry. Various bands (Band) are featured at concerts or festivals (Festival), which are characterized by their name and the members, or musicians (Musician). The code below needs to be updated to allow for the full functionality of the Main class, provided below. Assume that all getters and setters (for those variables that can be changed) are already written and you do not need to write them, and that the equals methods are overridden where they need to be. NOTE: The task should use the superclass constructor whenever possible, and respect the good practice of the object- oriented paradigm. public class Main { public static void main(String[] args) { Musician m1 = new Musician("Dave Grohl", "USA", 50, BandPosition.SINGER, 98); Musician m2 = new Musician("Pat Smear", "USA", 59, BandPosition.GUITARIST, 85); Musician m3 = new…
The purpose of this exercise is to allow the student to demonstrate their understanding of application development, the creation and use of classes and objects in Python, and using the other tools (selection, iterations, functions, etc.) we have learned this term. We will make a simple game called 'Stray Cat Strut' - Using the grid class discussed in Chapter 9, create a 20 x 20 cell game board- This game board represents a backyard- Create a class called animal with two attributes:-- an attribute called 'location' which is a grid coordinate (e.g., B3)-- an attribute called 'lives' which is an integer.- The animal class has the standard methods (init, str, etc.) plus one additional method:-- a method called 'move' that changes the animal's location one cell up (N), one cell right (E), one cell down (S), or one cell left (W). - Extend the animal class to a subclass called cat, and another subclass called dog- cat inherits the animal attributes and methods, but also has the following…
First, you need to design, code in Java, test and document a base class, Student. The Student class will have the following information, and all of these should be defined as Private: A first name (given name) A last name (family name/surname) Student number (ID) – an integer number (of type long) The Student class will have at least the following constructors and methods: (i) two constructors - one without any parameters (the default constructor), and one with parameters to give initial values to all the instance variables of Student. (ii) only necessary set and get methods for a valid class design. (iii) a reportGrade method, which you have nothing to report here, you can just print to the screen a message “There is no grade here.”. This method will be overridden in the respective child classes. (iv) an equals method which compares two student objects and returns true if they have the same student number (ID), otherwise it returns false. You may add other…
Java Question - Using the bottom code, create another class named "DigitalBook" as a subclass of the given "Book" class. Then, Make sure that the "DigitalBook" class contains two constructors: (1) one is the default constructor that takes no parameter, and (2) the other is a parameterized constructor that take 6 parameters. Be sure to use the “super” keyword in the constructors of the "DigitalBook" class. In the “main()” method of the “EX12_1” class, create four instances: “b1”, “b2”, d1”, and “d2”. Let “b1” and “b2” be the instances of the “Book” class, and let the “d1” and “d2” be the instance of the “DigitalBook” class. Be sure to use the specified constructor (as shown in attached picture) to initialize these instances. The Final Output is shown in the attached pictures. Please make sure that no errors show up in the Java Compiler when testing the code. Thank you. Add the following code to the "class Book" code (Below the ___ line). public class EX12_1{public static void…

by Using java: Write a class for the products in retail store with the following requirements. Each product class should have a name, an ID, a description, and a price. The product ID should be incremented automatically in the constructor each time an object is created. Create at least 4 different constructors for the class.
with this scenario the question asks to make a python program using tkinter python library for a GUI The program is build with the following instructions Your program should use the object-oriented principles to specify a billing class to accept input, validate fields, compute and display the power utility bill for customers as follows: It should specify a Billing class with customer attributes name, address, mobile no, base cost and units consumed. t should define a function for each attribute to validate each field as it is captured: name and address fields should accept a string, not a number, and should not be left blank, mobile no should be a number and should have 10 digits, units and base cost should be numbers and not be blank. It should compute the bill based on the pricing and the base rate provided in the text file (specified in Question 3.1d) for the three categories. You are required to create a text file with rates for each category and save the file as…

In java and UML diagram, Please show output and comment code out Source file: Each public class must be contained in a separate Java source file. Only one source file will have a main() method and this source will be named BlackjackGameSimulator.java. Other source/class names are up to you following the guidelines specified so far in the course. The format of the Java source must meet the general Java coding style guidelines discussed so far during the course. Pay special attention to naming guidelines, use of appropriate variable names and types, variable scope (public, private, protected, etc.), indentation, and comments. Classes and methods should be commented with JavaDoc-style comments (see below). Please use course office hours or contact the instructor directly if there are any coding style questions. JavaDocs: Sources should be commented using JavaDoc-style comments for classes and methods. Each class should have a short comment on what it represents and use the @author…
