Design a Java class named Rectangle to represent a rectangle. The class contains: v Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height. A no-arg constructor that creates a default rectangle. A constructor that creates a rectangle with the specified width and height. A method named getArea() that returns the area of this rectangle. A method named getPerimeter() that returns the perimeter. Write a Java test program that creates two Rectangle objects-one with width 4 and height 40 and the other with width 3.5 and height 35.9. Display the width, height, area, and perimeter of each rectangle in this order.

JAVA. THIS IS A PROGRAMMING ASSIGNMENT NOT A WRITING ASSIGNMENT IF YOU ANSWERED BEFORE DO NOT ANSWER AGAIN PLEASE DO NOT PASTE A PAPER     Design a class to store the following information about computer scientists⦁ Name⦁ Research area(s)⦁ Major contribution A scientist may have more than one area of research.⦁ Implement the usual setters and getters methods ⦁ Implement a method that takes a research area as an input and return thenames of scientists associated with that area ⦁ Implement a method that takes a word as an input and return the names ofscientists whose contribution mention that word Next, perform desktop research to find at least five prominent black computerscientists, with their research area(s) and major contribution, and store this data intoobjects of the class you designed. You can just hardcode this data. No user input needed.Define JUnit tests to check your research area and contribution search methods.

WRITE  JAVA CODE FOR THE FOLLOWING   Create a class named Pizza with the following data fields: description - of type String price - of type double The description stores the type of pizza (such as sausage and onion). Include a constructor that requires arguments for both fields and a method named display() to display the data. For example, if the description is 'sausage and onion' and the price is '14.99', the display() method should output: sausage and onion pizza Price: $14.99 Create a subclass named DeliveryPizza that inherits from Pizza but adds the following data fields: deliveryFee - of type double address - of type String The description, price, and address are required as arguments to the constructor. The delivery fee is $3 if the pizza ordered costs more than $15; otherwise it is $5. Add a display() method to the DeliveryPizza class. The display() method should print the information from the display() method in the super class (Pizza) in addition to the address and…

In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…

In a Java program, create an automobile class that will be used by a dealership as a vehicle inventory program. The following attributes should be present in your automobile class: private string make, private string model, private string color, private int year, private int mileage. Your program should have appropriate methods such as: constructor, add a new vehicle, remove a vehicle, update vehicle attributes. At the end of your program, it should allow the user to output all vehicle inventory to a text file.

JAVA Design a class named MyInteger. The class contains: An int data field named value that stores the int value represented by this object. A constructor that creates a MyInteger object for the specified int A get method that returns the int Methods isEven(), isOdd(), and isPrime() that return true if the value is even, odd, or prime, respectively. Static methods isEven(int), isOdd(int), and isPrime(int) that return true if the specified value is even, odd, or prime, respectively. Method equals(int) that return true if the value in the object is equal to the specified value.

Using Java Eclipse do the following program: Design a class named Rectangle to represent a rectangle. The class contains: Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height. A no-arg constructor that creates a default rectangle. A constructor that creates a rectangle with the specified width and height. A method named getArea() that returns the area of this rectangle. A method named getPerimeter() that returns the perimeter. Draw the UML diagram for the class then implement the class. Write a test program that create two Rectangle objects - one with width 4 and height 40, and the other with width 3.5 and height 35.9.  Display the width, heigth, area, and perimeter of each rectangle in this order.

Design a class named octopus that holds attributes for an octopus named weight and color. Include methods to set and get each of these attributes. Create the class diagram and write the class pseudocode that defines the class. Create a small program that declares two octopus objects and set the octopus's name weight and color attributes the program must also output each octopus's name weight and color after they are set. Please write out the pseudocode. I have a hard time with this.
