Class name: ParkingLot
Instance variables/Data members:
int vno: to store the vehicle number
int hours: to store the number of hours the vehicle is parked in the parking lot
double bill: to store the bill amount
Member methods:
void input(): to input the vno and hours
void calculate(): to compute the parking charge at the rate ₹ 3 for the first hour or the part thereof and ₹ 1.50 for each additional hour or part thereof.
void display(): to display the detail

Write a main method to create an object of the class and call the above methods.

Answer 1

import java.util.*;
public class ParkingLot
{
int vno; // vehicle number
double hours; // number of hours the vehicle is parked
double bill; // bill amt

void input()
{ System.out.println("Enter the vehicle number (only numbers allowed)and the no.of hours parked");
Scanner sn = new Scanner(System.in);
vno = sn.nextInt();
hours = sn.nextDouble();
}

void calculate()
{double h;
h = Math.ceil(hours); //anything less than an hr is also considered as an hr
if (h <= 1)
bill = 3;
else if (h > 1)
bill = 3 + (h - 1) * 1.50;
}

void display()
{ System.out.println("\n\nVEHICLE NO. " + vno);
System.out.println("NO. OF HRS PARKED " + hours);
System.out.println("BILL: " + bill + "");
}

public static void main(String Ljp[])
{ParkingLotob = new ParkingLot()
ob.input();
ob.calculate();
ob.display();
}}
