Practice questions on Java Classes and Objects – Find car rent using car type.

Define a class CARRENTAL with the following details :

• Class Members are : CarId of int type, CarType of string type and Rent of float type.
• Define GetCar() method which accepts CarId and CarType.
• GetRent() method which return rent of the car on the basis of car type, i.e. Small Car = 1000, Van = 800, SUV = 2500
• ShowCar() method which allow user to view the contents of cars i.e. id, type and rent.

Solution:

import java.util.*;

class CAR
{
    int CarId;
    String CarType;
    int Rent;
    
    public void GetCar(){
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter Car Id : ");
        CarId=sc.nextInt();
        System.out.println("Enter Car Type : ");
        CarType=sc.next();
    }
    public int GetRent(){
        if(CarType.equals("Small"))
           Rent = 1000;
        if(CarType.equals("Van"))
           Rent = 800;
        if(CarType.equals("SUV"))
            Rent = 2500;
        return Rent;
    }

    public void ShowCar(){
        System.out.println("Car Id : "+CarId);
        System.out.println("Car Type : "+CarType);
        System.out.println("Rent : "+GetRent());
    }
}

class CARRENTAL
{
   public static void main(String args[])
   {
     CAR ob=new CAR();  
     ob.GetCar();
     ob.GetRent();
     ob.ShowCar();
   }
}

Save the above Program with “CARRENTAL.Java” then compile it with the following command :

javac CARRENTAL.java   //compile the code

java CARRENTAL        //run the code

Output is :

Enter Car Id :
101
Enter Car Type :
SUV

Car Id : 101
Car Type : SUV
Rent : 2500
