Solved in 3 steps with 1 images
- 1. Create a Student class that implements the Person interface. As well as storing the students name and email, also store their course grade (e.g A, B, C) in a member variable. The grade should be accessible via a getGrade method. For the implementation of getDescription return a message along the lines of “A C grade student”, substituting the students actual grade.2. Create a Lecturer class that implements the Person interface. This class should also store the subject that the lecturer teaches. Add a getSubject method, and implement getDescription so that it returns a suitable message, e.g. “Teaches Biology”.3. Create a third class, Employee that implements the interface. This should also store the name of the department the Employee works in (available via getDepartment). Again, getDescription should return a suitable message.Temp Class - Create Temp class whos job is to hold a temp in degrees F and gives methods to get the temp in F, Celsius, and Kelvin. The class should follow the instance variable (field): ftemp (double type that holds F temp)Follow these methods with the class.. Constructor --Will accept Fahrenheit temperature as a double to store it in the ftemp field. setFahrenheit - The setFahrenheit method accepts a Ftemperature as a doubleto stores it in the ftemp field. getFahrenheit - Returns the value of the ftemp field, as a Fahrenheit temperature (no conversion required). getCelsius - Returns the value of the ftemp field converted to Celsius. [C e l s i u s = ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 )] getKelvin - Returns the value of the ftemp field converted to Kelvin. [K e l v i n = ( ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 ) ) + 273] Exemplify the temp class by writing a (test) program that is separate and promotes users for an F Fahrenheit temp. The program must create an…Create an abstract CardGame which contains a “deck” of 52 playing cards that uses a Card class that holds a suit and value for each Card object. It also contains an integer field that holds the number of cards dealt to a player in a particular game. The class contains a constructor that initializes the deck of cards with appropriate values (e.g., “King of Hearts”), and a shuffle() method that randomly arranges the positions of the Cards in the array. The class also contains two abstract meb. Create two child classes that extend CardGame. You can choose any games you prefer. For example, you might create a Poker class or a Bridge class. Create a constructor for each child class that initializes the field that holds the number of cards dealt to the correct value. (For example, in standard poker, a player receives five cards, but in bridge, a player receives 13.) Create an appropriate displayDescription() and deal() method for each child class.
- 3- Create a class named Player with a default name as "player", a default level as 0, and a default class type of "fighter". Feel free to add any other attributes you wish! Create an instance method in the Player class called attack that takes another player as a parameter. This function should compare the level of the two players, and return whether the player won, lost, or tied. Finally create a loop that allows the user to input a name and a class type for two players; the level of both players should be determined at random (between 1 and 99). Print out the name and attributes of each player, and have the first player attack the second. Print whether the player won, lost, or tied. Ask if the user wants to try again. (Python code)Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format. Student number PMark EMark MMark Mar#9186 81 64 72.00 1.2 Create a testStudents class. Do the following: -Write a static method called display() which receives…Modified Circle class and test file: Add a new attribute for color (or any other new attribute) Add get/set methods for this new instance variable, including data validation in set method (assuming background is black, i.e. circle color can't be black, reset to any non-black color if black is entered ). Add a new constructor to pass the color attribute as an argument. Add an instance method to display all properties of a Circle object. Create 2 objects using different constructors in test file, with invalid data. Use this test java file test java file: class CircleTest{ public static void main(String[] args){ int num = 10; Circle c1 = new Circle(0.001); Circle c2 = new Circle("black", -9); c1.display(); c2.display(); c1.setRadius( -1); c1.setColor("black"); c1.display(); }}
- class Point with instance variables as: xCoordinate(int) and yCoordinate(int). Write public instance methods (getters & setters) for each instance variable. Now, write a class Circle with private instance variables as radius and Pi (value is 3.14). Write public setter, getter for radius, Area method for calculating Area, Draw method for radius. Formula for calculating area=pi*r^2 Formula for calculating radius=Math.sqrt(xCordinate^2+yCordinate^2) Extend a Circle class from Point class such as Class Circle extends Point Write a Default constructor in Circle class that sets radius, xCoordinate&yCoordinate to some default value e.g. -1; Write a Parameterized constructor in Circle class which takes xCoordinate, yCoordinate and radius as a parameter. E.g. Circle (int xCoordinate, int yCoordinate, double radius) { this.xCoordinate= xCoordinate; this.yCoordinate= yCoordinate;…Description: Create a class named ComparableDog that extends Animal and implements Comparable interface. Implement the compareTo method to compare the Dogs on the basis of age. Write a test class to find the bigger age of two instances of ComparableDog Objects, and complement the ComparableDog class with the missing part. 1) The test program, the ComparableDog class, and its super class Animal are given as follows. // Main method public static void main(String[] args) { // Create two comparable Dogs ComparableDog dog1 = new ComparableDog(3); ComparableDog dog2 = new ComparableDog(4); System.out.println("Dog1:" + dog1); System.out.println("Dog2:" + dog2); if(dog1.compareTo(dog2) == 1) System.out.println("Dog1 is older than Dog2"); else if(dog1.compareTo(dog2) == -1) System.out.println("Dog1 is younger than Dog2"); else System.out.println("Dog1 and Dog2 have the same age"); }…Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.
- Write a PaypalAccount class to include both balance and accountID as the instance variables. Make sure each instance of this account will have a unique accountID. In other words, different account object should have different accountID (hint: class variable). 2.Write a Bank class with main method. In the main method, ask the user to input how many accounts (say numOfAccount) to be generated in the bank (assuming less than 1000). Then create an array to hold these numOfAccount of Account objects. For each Account object, generate a random balance in the range of 0.0-1000.0. a. Assume that your GSU campus ID is abc-de-fghi; search the array to see if there is an account with accountID as abc (the first three digits of your campus ID). If there is not an account with accountID as abc, then set the accountID of the last account in the array as abc; transfer all the balance of the first account to the account with accountID of abc b. Set the balance of the account with accountID of abc to…Create a class named "Hotel" (3 marks) - The class must have 4 attributes. (Choose any 4 attributes you want) - This class must have two constructors, Getter Methods, and Setter Methods. - toString() method should return the name of the hotel. In the main class that has the main method: - In the main method, Create 4 objects or more from the class Hotel and store them in a normal array. (3 mark) - Create an external method that takes the array as an argument. It will add all the elements of the normal array into an ArrayList. Then, call the method to test it and print all elements data from the ArrayList7)Circle Class Write a Circle class that has the following fields: radius: a double PI:a final double initialized with the value 3.14159 The class should have the following methods: Constructor. Accepts the radius of the circles as an argument. Constructor. A no-arg constructor that sets the radius field to 0.0. setRadius. A mutator method for the radius field. getRadius.An accessor method for the radius field. area. Returns the area of the circle, which is calculated as area. Returns the area of the circles, which is calculated as area= PI * radius * radius diameter. Returns the diameter of the cirlce, which is calculated as diameter = radius * 2 circumference. Returns the circumference of the circle, which is calculated as circumference = 2 * PI * radius Write a program that demonstrates the Circle class by asking the user for the circles's radius, creating a Circle object, and then reporting the cirlce's area, diameter, and circumference.
