Creating Car Class in Java

Problem:

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

Solution:

public class Car
{
 private String make;
 private String model;
 private int year;
 public Car(String make,String model,int year)
 {
  this.make = make;
  this.model= model;
  this.year = year;
 }
 
 public String setCarMake(String make)
 {
  this.make = make;
  return make;
 }
 
 public String getCarMake()
 {
  return make;
 }
 
 public String setCarModel(String model)
 {
  this.model = model;
  return model;
 }
 
 public String getCarModel()
 {
  return model;
 }
 
 public int setCarYear(int year)
 {
  this.year = year;
  return year;
 }
 
 public int getCarYear()
 {
  return year;
 }
 
 public String toString()
 {
  return "Car make: " + make + "      
  Car model: " + model + "      Car Year:" + year;
 }
 
 public static void main (String[] args)
 {
  Car car1 = new Car("Toyota", "Corolla" , 1996);
  Car car2 = new Car("Nissan", "Murano" , 2004);
  Car car3 = new Car("Infinity", "Mazda" , 2013);
  
  car1.setCarMake("BMW");
  System.out.println(car1);
  System.out.println(car1.getCarYear());

  car2.setCarModel("Altima");
  System.out.println(car2);
  System.out.println(car2.getCarMake());
  
  car3.setCarYear(2012);
  System.out.println(car3);
  System.out.println(car3.getCarModel());


 }
