Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…

(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…

TressetteYou are given the types: type colore = Spade | Coppa | Bastoni | Denari ;; type valore = Ace | Two | Three | Four | Five | Six |Seven | Jack | Knight | King ;; type mazzo = Null | Carta of carta and carta ={ c : colore ; v: valore ; mutable tl : mazzo };; (see the picture with cards) a. Write a function points : mazzo -> int = that given a deck of cards calculates its point score. The scoring is as follows: Ace is worth 1 point; Two, Three, King, Knight, Jack are each worth 1 3 ; and the rest do not contribute the the point total. The total point score is equal to the sum of the individual points, rounded down at the end. b. Write a function max_cards : mazzo -> mazzo = that takes a deck of cards and filters out everything except the greatest cards by value (valore) of each color. The order of cards by value is as follows: Three > Two > Ace > King > Knight > Jack > Seven > Six > Five > Four. Due to the size of the output, lists like…
PROGRAMMING LANGUAGE: C++ SUBJECT: OOP Task: Suppose you have a class Rectangle with data members width and height. The public member functions of class Rectangle are as follows: setValues(int w, int h); // to set values of width and height of objects of Rectangle class int Area();// to find area of an object of rectangle class biggerRectangle(Rectangle A, Rectangle B); prints the rectangle details which is bigger. Sample Code for passing object to a function is given below: #include <iostream> using namespace std; class CRectangle { int width, height; public: void set_values (int, int); int area () {return (width * height);} void copyData(CRectangle rect); }; void CRectangle::copyData(CRectangle rect) { width=rect.width; height=rect.height; cout<<"width of c = "<<width<<", height of c= "<<height<<endl; } void CRectangle::set_values (int a, int b) { width = a; height = b; } int main () { CRectangle a,b,c;…
