Answer 1

import java.util.*;
class ParkingLot
{
    private int vno, hours;
    double bill;
    public void input ( )
    { 
     Scanner sc=new Scanner (System.in);
     System.out.println ("enter Vehicle Number");
     vno=sc.nextInt( );
     System.out.println ("Enter Number of Hours")

     hours=sc.nextInt( );
}
public void calculate( )
{
    if(hours<=1)
    bill=hours*3
   else
   bill=3+(hours - 1)*1.5;
}
  public void display ( )
{
  System.out.println("Vehicle Number" + vno);
  System.out.println("Number of Hours" + hours);
  System.out.println("parking charges" + bill);
}
Public static void main ( )
{
  ParkingLot p = new Parking Lot ( );
  p.input ( );
  p.calculate ( );
  p.display ( );
}
}
