HI, i worked on ur java code: its working fine and put these lines in main function (Publis static void main(args))
ok::::....
public static void main(String args[])
{
HotelRoom hr = new HotelRoom("Eswar","double",8);
System.out.println("Estimate Price : "+hr.getEstimatedPrice());
System.out.println("Actual Price : "+hr.getActualPrice(6));
}
ok by the way indentation is quite confusing and u Didnt put code check for 7th day stay at the hotel, so better put =7 in the check cases of ur days variable ...days<=7 && days>0 ok
i changed the code to the folowing :
************************************************************
public class HotelRoom
{
final String singleRoom = "single";
final String doubleRoom = "double";
final String businessSuite = "business";
// define your fields here
private String guestname,roomtype;

private double estimatedprice,actualprice;
public HotelRoom(String guestname, String roomtype, int days)
{
// complete this method
this.guestname=guestname;
this.roomtype=roomtype;
this.days=days;
}
public String getGuestName()
{
return guestname;
}
