Create a class namely Circle and do the following: (i) Circle will have the following member variables: Point - an inner class having two members variables x and y representing the center and radius (a floating-point number) (ii) Crcate a method in the inner class namely getPoint() to print the point (x, y) that represents the circle center. (iii) Write a main method to create 10 random circles with the grid of (10, 10) and (70, 70).

Make a class that represents an average of test scores. Make the class take an unlimited number of scores and calculate the number of tests taken along with the average. Class name: TestScores Fields: - name : String - totalScore : double - numScores : int Methods: + TestScores(name : String) + addTestScore(earned : double) : void + getNumTestsTaken() : int + getAverage() : double Write in java and use test case 1 as an reference
Finish the TestPlane class that contains a main method that instantiates at least two Planes. Add instructions to instantiate your favorite plane and invoke each of the methods with a variety of parameter values to test each option within each method. To be able to test the functionality of each phase, you will add instructions to the main method in each phase.
The Delicious class – iterative methods The Delicious class must:• Define a method called setDetails which has the following header: public void setDetails(String name, int price, boolean available) This must find in the ArrayList the Chicken with the given name, change itspricePerKilo to the given price parameter and set whether it is in stock or not. A value of true for the available parameter means the chicken is in stock and a value of false means it is sold out (not in stock). Note that there will only be at most one Chicken object of the given name stored in the ArrayList.• Define a method called removeChicken that takes a single String parameter representing a chicken’s name. This method must remove from the ArrayList the Chicken object (if any) with the given name. The method must return true if a cheese with the given name was found and removed, and false otherwise.The Delicious class – challenge method In the Delicious class complete the findClosestAvailable method: This…
java code: Create a class Car and perform the following: - Declare public instance variables (name, model, color) as (String, int, and String) respectively. - Define set() method to set a car's name, model, and color. - Define show() method to print out the car's name, model, and color. In the main method: - Declare an array of the defined class Car with length 5. - Create three objects from Car and add them into the array. - Set the objects' values (name, model, color) using set method. - Print out the object's values (name, model, color) using show method

Create a class Course, which has one field: String courseName Create the constructor, accessor, and mutator for the class. Then, in the main method of this class, create an instance of the class with the name "CST1201". Write an equivalent while statement to replace the following for statement for (int i=2; i<100; i=i+2) { System.out.println(i); }
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…
this is for a python class 9.12 LAB: Product class In main.py define the Product class that will manage product inventory. Product class has three attributes: a product code, the product's price, and the number count of product in inventory. Implement the following methods: A constructor with 3 parameters that sets all 3 attributes to the value in the 3 parameters set_code(self, code) - set the product code (i.e. SKU234) to parameter code get_code(self) - return the product code set_price(self, price) - set the price to parameter price get_price(self) - return the price set_count(self, count) - set the number of items in inventory to parameter count get_count(self) - return the count add_inventory(self, amt) - increase inventory by parameter amt sell_inventory(self, amt) - decrease inventory by parameter amt Ex. If a new Product object is created with code set to "Apple", price set to 0.40, and the count set to 3, the output is: Name: Apple Price: 0.40 Count: 3 Ex. If 10…
