. Car Class Write a class named car that has the following fields: ▪ yearModel. The year Model field is an int that holds the car's year model. ▪ make. The make field is a String object that holds the make of the car, such as "Ford", "Chevrolet", "Honda", etc. ▪ speed. The speed field is an int that holds the car's current speed. In addition, the class should have the following methods. ■ Constructor. The constructor should accept the car's year model and make as arguments. These values should be assigned to the object's year Model and make fields. The constructor should also assign 0 to the speed field.

Build a class named car. This class is defined as follows: It has the fields: Car ID, Car model , Car make, Car color, Car year. Build a constructor that accepts the five parameters (Car ID, Car model , Car make,Car color, Car year). Override the method toString() to return the string representation of Car ID, Carmodel , Car make, Car color, Car year.
This is the question - Write an application that uses an abstract Insurance class and Health and Life subclasses to display different types of insurance policies and the cost per month. The Insurance class contains a String representing the type of insurance and a double that holds the monthly price. The Insurance class constructor requires a String argument indicating the type of insurance, but the Life and Health class constructors require no arguments. The Insurance class contains a get method for each field; it also contains two abstract methods named setCost() and display(). The Life class setCost() method sets the monthly fee to $36, and the Health class sets the monthly fee to $196. Code I was given - import java.util.*; public class Health extends Insurance { public Health() { // write your code here } public void setCost() { // write your code here } public void display() { // write your code here } } public…

(Date Class) Create a class called Date that includes three pieces of information as datamembers—a month (type int), a day (type int) and a year (type int). Your class should have a constructor with three parameters that uses the parameters to initialize the three data members. For thepurpose of this exercise, assume that the values provided for the year and day are correct, but ensurethat the month value is in the range 1–12; if it isn’t, set the month to 1. Provide a set and a get function for each data member. Provide a member function displayDate that displays the month, dayand year separated by forward slashes (/). Write a test program that demonstrates class Date’s capabilities.
