It has no class nameUse the GemotricObject class and its subclassess Cirlce and Rectangle to do the following: 1.Override Object’s toString() method in Circle class to returnthe status of Circle object. 2.Override Object’s toString() method in Rectangle class to return the status of Rectangle object. 3.Overide Object’s equals() method to compare two circle objects. 4.Overide Object’s equals() method to compare two Rectangle objects. 5.Test the above statements in the main method.Which of the following statements are false? (All that are not true). Group of answer choices A reference of type super class can refer to an instance of type subclass. A reference of type subclass can refer to an instance of type super class. A method in the super class can be overridden two different ways in two different subclasses. A method in the super class can be overridden by changing its signature in the subclass.
- What is the best first step to include in your implementation of equals(Object o) anytime you override it? Group of answer choices 1. Check if all instance variables of the invoking object and the input object are all equal. 2. Cast the passed in object as the class of the object invoking equals. 3.Check for identity (using ==). 4.Check if the invoking object (this) and the passed in object both implement the same interface, using instanceof. 5. No answer text provided.Java question please Create a class called Account that has the following attributes: Account Client - AccountHolder Double - Balance Date - DateCreated Account() Account(Client AccountHolder, Double Balance) getAccountHolder() - Client setAccountHolder(Client) - void getBalance() - Double deposit(Double) - Double withdrawal(Double) - Double getDateCreated() - Date toString() - String compareTo(Account) - Integer equals(Account) - Double Notes: The account holder attribute will link to the Account class that you created in problem 6. Your constructor and overloaded constructor should set the date created to the current date. Your deposit method should add to the balance Your withdrawal method should remove from the balance, as long as there is enough money to withdrawalWhich of the following keywords mark the beginning of the class definition?

- Which of the below is a valid and correct constructor method for 'Planet' class? The attributes of the Planet objects are: name, distance, yearDays. The constructor will set all attributes. Lütfen birini seçin: a. def __init__(name, distance, yearDays): self.name = name self.distance = distance self.yearDays = yearDays b. def Planet(self, name, distance, yearDays): self.name = name self.distance = distance self.yearDays = yearDays c. def Planet(self, name, distance, yearDays): Planet.name = name Planet.distance = distance Planet.yearDays = yearDays d. def __init__(self, name, distance, yearDays): self.name = name self.distance = distance self.yearDays = yearDays e. None of the othersWhich of the following is an example of dynamic dispatch? A: Assume you have an interface Car. There are three classes that implement the Car interface: Accord, Civic, Charger. Each of these classes has their own drive() method. There is an object myCar of type Car. When you invoke the drive() method, by calling myCar.drive() the correct implementation of drive() is chosen at runtime based upon the concrete class of myCar. B: Assume you have a variable myVariable. You have a for loop. The first time through the loop you set myVariable to an int, the next time you set it as a double, the next time a String, and finally an int. Each iteration of the loop myVariable has the correct type. C: Assume you have a class call Computation. Your computation class has a static method called add(). This method has three different versions:add(int x, int y)add(float x, float y)add(double x, double y)When you run Computation.add(x,y) the correct version of the method is chosen at compile time based…In method cook() of the CherryPie class, perform the following tasks: Increment class attribute total_pies.

- Create an application via NetBeans with named Pizza that storesinformation about a single pizza. It should contain the following:• Private instance variables to store the size of the pizza (eithersmall, medium, or large), the number of cheese toppings, the number ofbeef toppings, and the number of chicken toppings.• Constructor(s) that set all of the instance variables.• Public methods to get and set the instance variables.• A public method named calcCost( ) that returns a double that is thecost of the pizza.Pizza cost is determined by: Small: OR10 + OR 2 per topping Medium: OR 12 + OR 2 per topping Large: OR 14 + OR 2 per topping• A public method named getDescription( ) that returns a Stringcontaining the pizza size, quantity of each topping, and the pizzacost as calculated by calcCost( ).Which of the following statements are correct about the given code snippet? class A: def __init__(self, i = 0): self.i = i class B(A): def __init__(self, j = 0): self.j = j def main(): b = B() print(b.i) print(b.j) Group of answer choices Class B inherits A, but the attribute “i” in A is not inherited. Class B inherits A, thus automatically inherits all attributes in A. When you create an object of B, you have to pass an argument such as B(5). The attribute “j” cannot be accessed by object b. How many except statements can a try-except block have? Group of answer choices zero one more than one more than zeroImplement a class called Account which defines a modified banking account that can be created with a given balance and account name. It must be able to perform the following operations in the public interface: - Accepts an amount to deposit the balance - Withdraws an amount from the balance - Returns its balance - Returns its name - Displays its name and balance Write a Java application called AccountSystem to simulate an instance of the class. You need to use deposit and withdrawal methods in this program. USING INTELLIJ IDEA COMMUNITY
