A. 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, Car model, Car make, Car color, Car
year.
Build a method named display to print the values returned by toString() method.
Override the equals() method to compare the Car model, Car make, Car color of two Car objects. The method
returns true if all the values of these fields are the same, and false otherwise.
In the equals method you must check the following:
a. If you compare the Car object to itself, return true.!
b.
If you compare car object with another car object return true, otherwise return false. Hint use : instanceof
operator for this purpose.
Override the hashcode() method to return same hash codes for objects that are equal according to the equals()
method you built…
