- Rainfall Type Create a RainFall class that keeps the total rainfall in an array of doubles for each of the 12 months. Methods in the programme should return the following values: • the total annual rainfall; • the average monthly rainfall • the wettest month of the year • the month with the least amount of rain Demonstrate the class in its entirety. Validation of Input: Accepting negative amounts for monthly rainfall data is not permitted.Focus on classes, objects, methods and good programming style Your task is to create a BankAccount class. Class name BankAccount Attributes _balance float _pin integer Methods init () get_pin() check pin () deposit () withdraw () get_balance () The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0. get_pin () should return the pin. check_pin (pin) should check the argument against the saved pin and return True if it matches, False if it does not. deposit (amount) should receive the amount as the argument, add the amount to the account and return the new balance. withraw (amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was not. get_balance () should return the current balance.…Object Oriented Programming in JAVA You are part of a team writing classes for the different game objects in a video game. You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object. Also write a main method for each class in which that class is…
- Number Guessing Program using java: The player has to guess a number given in between a range. If the guessed number is right, the player wins else, loses. It also has the concept of limited attempts where the player has to guess the number within the limited attempts given. Note: It must incorporates the following OOP components: - Classes - Objects - Constructors - Class Variable - Object MethodExercises abstract class • Design a new Triangle class that extends the abstract GeometricObject class: • Draw the UML diagram for the classes Triangle and GeometricObject • Implement the Triangle class • Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled: • The program should create a Triangle object with these sides and set the color and filled properties using the input • The program should display the area, perimeter, color, and true or false to indicate whether it is filled or notPet ClassDesign a class named Pet, which should have the following fields: name: The name field holds the name of a pet. type: The type field holds the type of animal that a pet is. Example values are "Dog", "Cat", and "Bird". age: The age field holds the pet’s age. The Pet class should also have the following methods: setName: The setName method stores a value in the name setType: The setType method stores a value in the type setAge: The setAge method stores a value in the age getName: The getName method returns the value of the name getType: The getType method returns the value of the type getAge: The getAge method returns the value of the age Once you have designed the class, design a program that creates an object of the class and prompts the user to enter the name, type, and age of his or her pet. This data should be stored in the object. Use the object’s accessor methods to retrieve the pet’s name, type, and age and display this data on the screen. *** I need help…

Write appropriate accessor and mutator methods. Also, write a tester program(Console and GUI Program) that creates three instances/objects of the Library Items class. Extending Library Item Class Library and Book Classes: Extend the Library Item class in (1) with a Book class with data attributes for a book’s title, author, publisher and an additional attributes as number of pages, and a Boolean data attribute indicating whether there is both hard copy as well as eBook version of the book. Demonstrate Book Class in a Tester Program (Console and GUI Program) with an object of Book class.Circle ClassWrite a Circle class that has the following fields:• radius: a double• PI: a final double initialized with the value 3.14159The class should have the following methods:• Constructor. Accepts the radius of the circle 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 asarea = PI * radius * radius• diameter. Returns the diameter of the circle, which is calculated asdiameter = radius * 2• circumference. Returns the circumference of the circle, which is calculated ascircumference = 2 * PI * radiusWrite a program that demonstrates the Circle class by asking the user for the circle’s radius, creating a Circle object, and then reporting the circle’s area, diameter, and circumference.
- True/False: When instantiating an object of an abstract class, you can do it with the keyword new.class City(object): county = "Lake" population = 3000000 def -_init__(self, name, state): self.name = name self.state = state def region(self): return "Midwest" a) create an instance of this object, called X, for Chicago, Illinois b) return the population of the instance X c) change the county of the instance X from Lake to Cook d) return the name of the state of the instance X d) call the method region() on the instance XParent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…
