Question

Java

Write a class called Car that contains instance data that represents the make, model, and year of the car.

Define the Car constructor to initialize these values

Include getter and setter methods for all instance data and a toString method that returns a one-line description of the car.

Add a method called isAntique that returns a boolean indicating if the car is an antique (if it is more than 45 years old).

Create a driver class called CarTest, whose main method instantiates and updates several Car objects

Must have two constructors, one accepts nothing and another overloaded constructor that accepts parameters.

Must have accessor and mutator methods for each instance variable, and the toString method

Must test ALL (the two constructors, the accessors, and mutators for each variable and the other methods if there are any) methods explicitly in the driver class’s main method with at least two objects.

Addon:

Create an array of five objects of the class you have created. Use a for loop to display the five objects first. Then test all methods using the objects in the array and finally print out each object using a for loop again.

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You

Output:

Car : Make=Ford, Model:T-Model, Year:1927
T-Model is Antique.
Car : Make=Honda, Model:Civic, Year:2018
Civic is not Antique.
Car : Make=Volkswagen, Model:Ameo, Year:2019
Car : Make=Volkswagen, Model:Polo, Year:2016
Car : Make=BMW, Model:Gran Coupe, Year:2019
Car : Make=Hyundai, Model:Grand i10, Year:2019
Car : Make=Renault, Model:Duster, Year:2017
