Classes and Objects) Hand-write a complete Java class that can be used to create a Car object as described below. a. A Vehicle has-a: i. Registration number ii. Owner name iii. Price iv. Year manufactured b. Add all instance variables C. The class must have getters and setters for all instance variables d. The class must have two constructors, a no-args and a constructor that receives input parameters for each instance variable.

Internally your program should have two Java classes: ValidatorNumeric (superclass) ValidatorString (subclass) The subclass ValidatorString extends ValidatorNumeric class, forming a hierarchy of two classes. Add a separate main class with the main() method to test all public methods in both ValidatorNumeric and ValidatorString classes. The main() method should create the necessary objects and run the user interaction as shown above. The ValidatorNumeric class is responsible for capturing user prompt and a range of valid numeric inputs. Its methods display the prompt and accept input from the user. It should provide the following public interface: // Default constructor ValidatorNumeric() // Specific constructor taking params as follows: ValidatorNumeric( String prompt, int min, int max ) // Another specific constructor taking params as follows: ValidatorNumeric( String prompt, double min, double max ) // Method that shows user prompt and gets an int from the user: public...

Summary In this lab, you create a derived class from a base class, and then use the derived class in a Python program. The program should create two Motorcycle objects, and then set the Motorcycle’s speed, accelerate the Motorcycle object, and check its sidecar status. Instructions Open the file named Motorcycle.py. Create the Motorcycle class by deriving it from the Vehicle class. Call the parent class __init()__ method inside the Motorcycle class's __init()__ method. In theMotorcycle class, create an attribute named sidecar. Write a public set method to set the value for sidecar. Write a public get method to retrieve the value of sidecar. Write a public accelerate method. This method overrides the accelerate method inherited from the Vehicle class. Change the message in the accelerate method so the following is displayed when the Motorcycle tries to accelerate beyond its maximum speed: "This motorcycle cannot go that fast". Open the file named MyMotorcycleClassProgram.py. In the...

public class Cat { private int age; public Cat (int a) { age = а; } public int getAge() { return a; } } Which of the following best explains why the getAge method will NOT work as intended? The instance variable age should be returned instead of a, which is local to the constructor. The variable age is not declared inside the getAge method. The getAge method should be declared as private. The getAge method should have at least one parameter.

Write a code for a banking program.a) In this question, first, you need to create a Customer class, this class should have:• 2 private attributes: name (String) and balance (double)• Parametrized constructor to initialize the attributes• Methods:i. public String toString() that gives back the name and balanceii. public void addPercentage; this method will take a percentage value andadd it to the balanceb) Second, you will create a driver class and ask the user to enter 6 customers’ informationand then you will create an array of Customer objects.c) Then you use this array used for various operations as shown in the output.• Using the array of customer objects, you need to search for all customers whohave less than 150ドル• Using the array of customer objects, you need to get the average balance of thebalances in this array• Using the array of customer objects, you need to get the customer with thehighest balance and lowest balance• Using the array of customer objects, you need to show all...

Use Java Programming Language Create a Loan Account Hierarchy consisting of the following classes: LoanAccount, CarLoan, PrimaryMortgage , UnsecuredLoan, and Address. Each class should be in it's own .java file. The LoanAccount class consists of the following properties: principal- the original amount of the loan. annualInterestRate - the annual interest rate for the loan. It is not static as each loan can have it's own interest rate. months - the number of months in the term of the loan, i.e. the length of the loan. and the following methods: a constructor that takes the three properties as parameters. calculateMonthlyPayment() - takes no parameters and calculates the monthly payment using the same formula as Assignment 1. getters for the three property variables. toString() - displays the information about the principle, annualInterestRate, and months as shown in the example output below. The CarLoan class which is a subclass of the LoanAccount class and consists of the...

Java:

The non-static class level variables and non-static methods of a class are known as a. instance members b. object behaviors c. object attributes O d. object references

1)Create a complete Java class that can be used to create a Computer object as described below:A Computer has a:- Manufacturer- Disk Size- Manufacturing Date- Number of coresa) Add all instance variables (data encapsulation is expected).b) The class must have getters and setters for all instance variables.c) The class must have two constructors: a no-arg constructor and a constructor thatreceives input parameters for each instance variable.d) Implement a toString() method for your class. 2)Write a Java program TestComputer, which creates three Computer objects with the informationbelow:a) - Manufacturer: Dell- Disk Size: 1189160321024 bytes- Manufacturing Date: April 1, 2020- Number of cores: 2b) - Manufacturer: Apple Inc- Disk Size: 269283712040 bytes- Manufacturing Date: March 31, 2020- Number of cores: 4c) Create your own Object. You can mimic your actual personal computer or use a no-argsconstructor.Print the three objects using toString() method to show all data fields

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...
