You will be writing a scheduling application allowing a convention center to schedule events. This program will contain two different classes: Date and Event. Both classes should be defined on their own .py modules. You may use the Date class we designed in class in lecture 18 (which will also be posted on Canvas). The Event class should have the following attributes: event_date (which should be a Date object) event_name start_hour: Uses a 24-hour clock, so should be a value between 0 and 23 endHour: Uses a 24-hour clock, so should be a value between 0 and 23 The Event class should have the following methods: __str__. Return a string representation of all important info about this Event: The name of the event, the start and end times (you can simply print their value i.e. from 14 to 16) and the Date. Properties and setters for the attributes. A constructor which takes a name, start and end hours, and a Date object. Note: For sake of simplicity, each event will only take one day…

ASSIGNMENTWrite a Java program that meets these requirements.• Create a NetBeans project named LastnameAssign1. Change Lastname to your last name. For example, my project would be named NicholsonAssign1.• In the Java file, print a welcome message that includes your full name.• The program should prompt for an XML filename to write too The filename entered must end with .xml and have at least one letter before the period. If it does not, print a warning and prompt again. Keep nagging the user until a proper filename is entered.• Prompt the user for 3 integers.o The three integers represent red, blue, and green channel values for a color.o Process the numbers according to the instructions belowo Once you have handled the 3 input values, prompt the user againo Keep prompting the user for 3 integers until the user enters the single word DONEo Reading input should not stop for any reason except for when the user enters DONE.o The user will not mix DONE and the numbers.

public interface IDate{ * Since this is the first interface you will use, a couple of notes: * 1) Do not edit this document. Any changes will be done and then re-uploaded * 2) In additon to implementing all of the following methods you need a detailed Constructor nt month, int day){... Implementation not shown...); * 3) The following needs to be added to your header: implements IDate public class Date implements IDate{ * 4) There will be a tester file for this project. Write it to specifications, or it will not work! * 5) You will need to store 3 integers representing day, month and year I also stored an int array that stores the days of the month! */ //Moves this IDate forward in time by the given number of days public Date(int year, int month, int day) { public void addDays(int days) { //Moves this IDate forward in time by the given number of weeks //This one is easy once you have done addDays! public void addWeeks(int weeks) { //Returns the number of days that this Date must be…

Your project should minimally demonstrate: Maven support with a pom.xml and appropriate dependency/dependencies A Java class to test Two (2) JUnit Test cases One (1) JUnit Test Suite At least three (3) different assertion methods used please follow these instructions exactly. Language must be java.
1. Create a java project in NetBeans and name the project Hw01. 2. Design and implement a class named Account that contains: • A private int data field named id for the account (default 0).• A private double data field named balance for the account (default 0).• A private double data field named annualInterestRate that stores the current interest rate (default 0). Assume all accounts have the same interest rate.• A private Date data field named dateCreated that stores the date when the account was created.• A no-arg constructor that creates a default account.• A constructor that creates an account with the specified id and initial balance.• The accessor and mutator methods for id, balance, and annualInterestRate.• The accessor method for dateCreated.• A method named getMonthlyInterestRate() that returns the monthly interest rate. (Hint: Monthly interest rate is annualInterestRate/12.)• A method named getMonthlyInterest() that returns the monthly interest. (Hint: Monthly interest is…
Computer Science Write a program to design a graphical user Interface using JavaFX without FXML and make a main class and subclasses for a project of your Interest that contains the following features add four buttons for:  Add information or add service or add booking..etc  Update information, update service, update booking.. etc  Delete information, delete service, delete booking..etc  Search information, search service, search booking..etc  Add a logo at the top of the interface. You Program should follow the class Design Guidelines. Your Program should include Inheritance feature, use Interface, encapsulation. Draw a UML Diagram that represent your project. For example, Add Booking: The system will ask the user to enter the user information (Name, Phone number, Date Booked, service or anything related to your project. Once the Booking is added a message Booking confirmed with name and service, Date Booked will be displayed.  The System need to check if the same Phone number…
Your module should be named “loc.py”. Include instance variables for all data about a location (name, summary, details.) The constructor should allow creating a location with whatever name, summary, and details you want, but a newly create Locale has not yet been visited. The string representation of a Locale should be its summary if it has not yet been visited, otherwise it should be a brief message including its name, such as “You are at Sandy Beach.” Include other observer and mutator methods as needed.
Project 2 statement ANSWER IN SINGLE FILE JAVAPlease read this entire statement carefully before you start doing anything… This project involves implementing a simple university personnel management program. The program contains three kinds of objects: Staff, student and faculty. For each object, the program stores relevant information such as university ID, name, etc. Different information is stored depending on the type of the object. For example, a student has a GPA, a faculty has a title and department (professor, mathematics).For each of any class data member, your program must include the getters and the setters, and each class must include at least two constructors. The goal of this Project is to demonstrate the use of inheritance, abstract classes, abstract methods, and method overriding. For a student, we need a: full name id gpa Number of credit hours currently taken For a faculty, we need a: full name id department (mathematics, engineering or english) Rank (professor or…

Create a new project named lab10. You will be implementing two classes: A SolarSystem class, and a Planet class. The SolarSystem contains Planet objects stored in a vector. A UML diagram for the Solar System and Planet classes The first part you should implement is the Planet class. Don't add the SolarSystem files to the project at the beginning, just work on the Planet class. Test the different overloaded operators as we did during lecture for your Planet class, and then move on to the SolarSystem class. The SolarSystem default constructor should resize the vector to zero. The default constructor values for Planet can be whatever you’d like, but make the mass a very small number, so later on when you're looking for the largest planet, it doesn't use the default Planet value. The addPlanets() method will take a number as an argument for the number of Planets that will be in your SolarSystem. So if you call addPlanets with 5 as an argument, there will be 5 Planets to add to the…
