Question

Create a class called Car (Car.java). It should have the following private data members:

• String make

• String model

• int year

Provide the following methods:

• default constructor (set make and model to an empty string, and set year to 0)

• non-default constructor Car(String make, String model, int year)

• getters and setters for the three data members

• method print() prints the Car object’s information, formatted as follows:

Make: Toyota

Model: 4Runner

Year: 2010

public class Car {

}

Answer 1

Java Program :

public class Car
{
    private String make, model;   // declared all required variables as private
    private int year;
    
    Car()    // default constructor to initialize all variables
    {
        make = "";
        model = "";
        year =0;
    }
    
    Car(String make, String model, int year) // Parameterized constructor to give values to variables
    {
        this.make = make;         // this keyword is used to represent the class variable
        this.model = model;
        this.year = year;
    }
    
    void setMake(String make)    // setter for make
    {
        this.make = make;
    }
    
    String getMake()           // getter for make
    {
        return make;
    }

    void setModel(String model) // setter for model
    {
        this.model = model;
    }
    
    String getModel()        // getter for model
    {
        return model;
    }

    void setYear(int year)  // setter for year
    {
        this.year = year;
    }
    
    int getYear()         // getter for year
    {
        return year;
    } 
    
    void print()        // prints all data
    {
        System.out.println("Make: "+make);
        System.out.println("Model: "+model);
        System.out.println("Year: "+year);
    }
    
}

public class Main
{
        public static void main(String[] args) 
        {
                Car c = new Car("Toyota", "4Runner", 2010);   // creates a new object of Class Car and intializes with a constructor
                c.print();            // calls the print() method of Class Car
        }
}
