using Java, create a class where the user will receive a notification if they have been inactive for a week. Make sure each class has at least two attributes (instance variables) and two methods, plus a constructor to initialize any attributes as needed. Once you have written the classes, use the JUnit features in NetBeans to create unit tests for your two classes.
Q# A program that has no graphical user interface and only takes input through the command line only has a model and a controller. It does not have a view. The answer: is FALSE. Please explain with example. Q# What is NOT an effect of the SOLID principles? The answer: A high-level class depends on specific low-level classes and not interfaces. Please explain why. Q# Assume you are considering writing a method and are deciding what should happen when given input that is outside of perfect input. Which of the following is not a way to handle this? Answer: Use better JUnit testing. Subject: Java Programming
I need help create this java code that would output like it's described in the image below : public class Artist { // TODO: Declare private fields - artistName, birthYear, deathYear // TODO: Define default constructor // TODO: Define second constructor to initialize // private fields (artistName, birthYear, deathYear) // TODO: Define get methods: getName(), getBirthYear(), getDeathYear() // TODO: Define printInfo() method // If deathYear is entered as -1, only print birthYear }
solve this java question SpecificationsWhat You Must ImplementYou must define a class named MediaRental that implements the MediaRentalInt interface functionality(index A). You must define classes that support the functionality specified by the interface. The followingspecifications are associated with the project:1. Define a class named MediaRental. Feel free to add any instance variables you understand are needed or anyprivate methods. Do not add any public methods (beyond the ones specified in the MediaRentalInt interface).2. The media rental system keeps track of customers and media (movies ,music albums and games). A customerhas a name, address as string , a plan and two lists. One list represent the media the customer is interested inreceiving and the second one represents the media already received (rented) by the customer. There are twoplans a customer can have: UNLIMITED and LIMITED. UNLIMITED allows a customer to receive as many mediaas they want; LIMITED restricts the media…

Game class instructions:• Game class has three attributes: points (which represent the number of points awarded when winning the game), status (false if the game has not been played and true if the game has been played), and description (which is a text description of the game). Note that description attribute is a read-only variable. • In the constructor, initialize points to zero, status to false, and description to the given parameter.• isPlayed method returns true if the game has been played, and false otherwise.• getPoints is a getter method for points attribute.• play method is an abstract method.• Override toString method to return the game description.• Override equals method so that two games are the same if their descriptions are the same. :instructions class ) HangMan• HangMan is a game in which a player tries to guess a word based on a given hint.

In Java, Create a class Rectangle with double attributes length and width. The default constructor should set these attributes to 1. Provide methods that calculate the rectangle's perimeter and area, as well as accessors and mutators for both data fields. The mutator methods for length and width should verify that the number being passed in is larger than 0.0 and less than 20.0 -- if it doesn't fit those criteria, the value of the field should not be changed.Write a Driver class in the same file to test your Rectangle class. It should prompt the user to enter a length and width of a rectangle, and then print out the area and perimeter of the rectangle. (Use the mutators to set the length and width of the rectangle, not the constructor.)
(a) Write the Java code for the convertJPG() method in the Facade class. Youmay assume that all other methods in all the classes have been fully implemented.For example, in the Facade class, the constructor Facade() will create thevariable state and make it point to the image that needs to be converted. You mayfurther assume that the convert() method in the JPG class will convert the imagepointed to by state to JPG format. (b) Write the Java code for the main() method in the FacadeDemo class. You mayassume that all the other classes are fully implemented. In the main() method, firstcreate an object instance of the Facade class, and then convert the image pointed toby state to JPG.

What indicates that a class definition is complete? A. The first line of code that is not indented. B. The classEnd statement. C. The defEnd statement. D. Nothing. Class definitions never end. How are instance variables within an object's method referenced? A. by attaching 'self' and a period before the instance variable's name B. by attaching the method name and a period before the name of the instance variable. C. by specifiying the instance variable's name D. by specifying the name of the class and the instance variable. Which of the following statements correctly shows the first line of a class definition for Rectangle? A. class Rectangle: B. def class Rectangle: C. class Rectangle(): D. class Rectangle(self):
QI. Write a program in BlueJ using the following hints. 1. Create a class named Book and declare the fields author, title and pages with suitable field types. 2. Declare the constructor and initialize the fields author and title with the assigned constructor parameter. 3. Name the constructor parameter as your own. 4. Add two accessor methods to the class getAuthor, getTitle and getPages—that return the author and title fields as their respective results. Add mutator method to change the pages of the Book class. 5. Add two methods, printAuthor and printTitle, to this Book class project. These should print the author and title fields, respectively, to the terminal window.
