This is the question -
Create a UsedCarException class that extends Exception; its constructor receives a value for a vehicle identification number (VIN) that is passed to the parent constructor so it can be used in a getMessage() call. Create a UsedCar class with fields for VIN, make, year, mileage, and price. The UsedCar constructor throws a UsedCarException when the VIN is not four digits; when the make is not Ford, Honda, Toyota, Chrysler, or Other; when the year is not between 1997 and 2017 inclusive; or either the mileage or price is negative.
Write an application that establishes an array of at least seven UsedCar objects and handles any Exceptions. Display a list of only the UsedCar objects that were constructed successfully.
Here is the code I have -
public class ThrowUsedCarException {
public static void main(String[] args) {
// Write your code here
}
}
public class UsedCar {
String vin;
String make;
int year;
int mileage;

Write a program to create a class” Fan “to represents features of a fan as follows:
“Fan “should contain following details fanType, manufacturer, model, isOn.
Use constructor to initialize data members of the Fan class.
Create function on() and off() to switch on and off the fan respectively.
Create a function speedup() is to increase the speed of the fan by 1 if speed of the Fan greater than 5 it should throw a custom exception.
Create another function speeddown() is to decrease the speed of the fan by 1 if speed of the Fan less than 0 it should throw a custom exception.
Make a menu driven program.
Modify the attached code:
Create a new class called CalculatorWithMod. This class should be a sub class of the base class Calculator. This class should also have an additional method for calculating the modulo. The modulo method should only be seen at the sub class, and not the base class!
Include exception handling for instances when dividing by 0 or calculating the modulo with 0. You would need to use throw, try, and catch.
The modulo (or "modulus" or "mod") is the remainder after dividing one number by another.Example: 20 mod 3 equals 2Because 20/3 = 6 with a remainder of 2

- Write a class named StockPrices . The class constructor should accept an array of stock prices as its argument. The class should have a member function that returns the average of the stock prices. If any stock price in the array is negative or greater than 5000, the class should throw an exception. Demonstrate the class in a program.arrow_forwardCreate a flowchart and modify the code.

Modify your application such that the properties will be read from a text file called “Cycle.txt”. Directions Examine your application for the class called Cycle. Add an appropriate throws statement in the main method. Create a reference to a File class with the appropriate name of a text file (Cycle.txt). Note: Cycle.txt was created in the previous assignment, CycleFileOutput. In your code, check that the text file does exist. Input the values from the file to memory. Close the file.arrow_forward
- ArgumentException is an existing class that derives from Exception; you use it when one or more of a method’s arguments do not fall within an expected range. Write the application SwimmingWaterTemperature containing a variable that can hold a temperature expressed in degrees Fahrenheit. Within the class, create a method that accepts a parameter for a water temperature and returns true or false, indicating whether the water temperature is between 70 and 85 degrees and thus comfortable for swimming. If the temperature is not between 32 and 212 (the freezing and boiling points of water), it is invalid, and the method should throw an ArgumentException. In the Main() method, continuously prompt the user for data temperature, pass it to the method, and then display the following messages indicating whether the temperature is comfortable, not comfortable, or invalid: X degrees is comfortable for swimming. X degrees is not comfortable for swimming. Value does not fall within the expected…arrow_forwardJava Problem:Create a Class named Bishop. Make sure the class cannot be inherited. If there have already been 5 objects initiated for this class, trying to initiate the 6th object, the constructor will throw a user-defined exception BishopCreationLimitExceeded. This class has an instance method named printObjectNumber which will print the object creation sequence number for the object for which you are calling the method as follows: This Bishop Object number is 3. Here, 3 is the object creation sequence number that is the third call to new Bishop() in your code that initiated the object. The BishopCreationLimitExceeded class sets the exception message (using super call in the constructor) as follows: The maximum number of bishop objects can be 5. You can define instance variables in the Bishop class if you need them.arrow_forwardIn Java Attachedarrow_forward
