(The Triangle class) Design a class named Triangle that extends GeomericObject. The class contains:  Three double data fields named side1, side2, and side with default values 1.0 to denote three sides of the triangle. A no-arg constructor that creates a default triangle. A constructor that creates a triangle with the specific side1, side2, and side3. The accessor method for the three data fields. A method named getArea() that returns the area of this triangle. A method named getPerimeter() that returns the perimeter of this triangle. A method named toString() that returns a string description for the triangle. Note:- Please write a java code and also need an output for this program. (Also, let me know with what name file should be saved to get output)

Question: Submit document with methods for your automobile class, and pseudo code indicating functionality of each method. Example: public String RemoveVehicle(String autoMake, String autoModel, String autoColor, int autoYear) If              values entered match values stored in private variables              remove vehicle information else              return message indicating mismatch   Assignment details/background 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 makeprivate string modelprivate string colorprivate int yearprivate int mileage Your program should have appropriate methods such as: default constructorparameterized constructoradd a new vehicle  methodlist vehicle information (return string array)remove a vehicle methodupdate vehicle attributes method. All methods should include try..catch constructs. Except as noted all methods should return a…

Q3: Define a class named Car that has the following specifications:Two attributes:plateNumber: to keep car’s plate number as String value. speed: to keep car’s current speed as integer value.Seven methods:Car( String pn , int s), a constructor method used to initialize the instantiated objects. setPlateNumber( String pn), act as a set method for the attribute plateNumber. setSpeed( int s), act as the set method for the attribute speed.getPlateNumber(), act as the get method for the attribute plateNumber.getSpeed(), act as the get method for the attribute speed.fines (), returns the amount of traffic fine (500 SR) if car’s speed exceeds 120 k/h, otherwise 0. main(...), act as the main method for the program, and it should do the following:1. Instantiate three objects, namely car1, car2, and car3, using the populated constructor.2. Change the speed value of the first car (car1) to 130.3. Change the plate number of the second car (car2) to “Java123”.4. Print the following statement,The…

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…

!! E! 4 2 You are in process of writing a class definition for the class Book. It has three data attributes: book title, book author, and book publisher. The data attributes should be private. In Python, write an initializer method that will be part of your class definition. The attributes will be initialized with parameters that are passed to the method from the main program. Note: You do not need to write the entire class definition, only the initializer method lili lilı

answer the following: all questions 1, 2 and 3 attached below;

1) Do you think it is possible to create another constructor with the same set of parameters? For example, adding the following constructor to Volunteer. Place a check (​​✓)​​ beside your answer.Volunteer(): name_("Default"), branch_("CSU Long Beach") { } Yes, because you can overload constructors much like how you overload member functions. No, because the program will not know which constructor to use. No, because the body of the constructor is empty. 2) Much like constructors, member functions can also be overloaded. Write the name of Volunteer's overloaded member function. Take note that member function overloads need to have the same return type. 3) How do you think the compiler knows which member function overload it should call? Place a check (​​✓)​​ beside your answer. It checks the name of the member function that was called. It compares the number of arguments and their data types with the member function's parameters. It always calls the overload with the least number of…

(Java) The Abstract Art Class Write an abstract class as follows: The class is named Art It inherits from the Comparable interface It has a private String member variable named name It has a private String member variable named artist It has a private int member variable called year It has a default constructor that assigns the values "No name" to name, "No artist" to artist and -1 to the year. This default constructor calls the three argument constructor. It has a three-argument constructor to assign values to the name, artist and year variables. It has a copy constructor that makes a copy of another non-null Art object It has getters and setters for the name, artist and year variables It has a toString() method that creates a string of artist, with name and year tabbed once on subsequent lines (see sample output) It has an equals method that compares this Art to another Object It has a compareTo method that compares in this order: 1) artist, 2) name, 3) year This class contains no…
