Trouble with UseCarRental program I have to write

[Madmax40ao]

First part having no trouble with this

public class CarRental
{
   private String name = "";
   private int zipCode = 00000;
   private String carSize = "";
   private int daysRented = 0;
   private double totalFee = 0.00;
   private String chauffer = "";
   double chaufferFee = 0000.00;
   public CarRental(String n, int zc, String cs, int dr)
   {
      name = n;
      zipCode = zc;
      carSize = cs;
      daysRented = dr;
   }
 
   private double RentalFee(String carsize)
   {
      double fee = 0.00;
      if(carsize.equals("economy"))
      {
         fee = 29.99;
      }
      else if(carsize.equals("midsize"))
      {
         fee = 38.99;
      }
      else if(carsize.equals("fullsize"))
      {
         fee = 43.50;
      }
      else if(carsize.equals("luxury"))
      {
         fee = 79.99;
      }
      return fee;
   }
}
Second part also no trouble with this.
public class LuxuryCarRental extends CarRental
{
   public LuxuryCarRental(String n, int zc, String cs, int dr, String ch)
   {
      super(n, zc, cs, dr);
      if (ch.equals("y"))
         chaufferFee = 200.00;
   }
}
Final part is where the trouble is..
import java.util.*;
import java.text.*;
public class UseCarRental
{
   public static void main(String args[])
   {
      Scanner input = new Scanner(System.in);
      System.out.println("Enter your full name: ");
      input.next();
      String name = input.nextLine();
      System.out.println("Enter your zip code: ");
      int zipCode = input.nextInt();
      System.out.println("Enter the car size you would like to rent: \n"
            + "economy\n"
            + "midsize\n"
            + "fullsize\n"
            + "luxury?");
      String carSize = input.next();
      System.out.println("How many days would you like to rent this vechile for?");
      int daysRented = input.nextInt();
      if (carSize.equals("luxury"))
      {
         System.out.println("Would you like a chauffer? (y or n)");
         String chauffer = input.next();
         LuxuryCarRental rentIt = new LuxuryCarRental(name, zipCode, carSize, 
         daysRented, chauffer);
         rentIt.display();
      }
      else
      {
         CarRental rentIt = new CarRental(name, zipCode, carSize, daysRented);
         rentIt.display();
      }
}
      private void display()
      {
         double fee = totalFee(carSize);
         System.out.println("Renters Name: " + name);
         System.out.println("Renters Zip Code:" + zipCode);
         System.out.println("Car Rented:" + carSize );
         System.out.println("Daily Rental Fee:" + fee);
         System.out.println("Total Days Rented:" + daysRented);
         double days = (double)daysrented;
         totalFee = (fee * days) + (chaufferFee * days);
         DecimalFormat df = new DecimalFormat("#.##");
         String trf = df.format(totalFee);
         System.out.println("Total Fee:" + tf);
      }
   }

1.) You are calling the display method on the Car rental object but the method is not in the Car rental class. So move that method to the CarRental class.
2.) If you want to be able to call that method outside that class then you need to make it public too.
3.) You have a line

double days = (double)daysrented;

which is incorrect because the variable called daysRented (with a capital R). Java is case sensitive.
4.) You have another incorrect line with

double fee = totalFee(carSize);

What are you trying to achieve with that?
5.) You also have another typing mistake with

 System.out.println("Total Fee:" + tf);

which should be

System.out.println("Total Fee:" + trf);

[Madmax40ao]

ok so i fixed some of the issues but i don't understand what you mean by #1 and 2 with the methods.

[r035198x]

You have

CarRental rentIt = new CarRental(name, zipCode, carSize, daysRented);
rentIt.display();

For you to call the method rentIt.display(), it must be in the CarRental class because you are calling it on rentIt which is a reference to an object of the CarRental class. In your code that method is in the UseCarRental class instead so that won't work.

[itsraghz]

Look at the lines 75 to 77 in your code pasted above.

LuxuryCarRental rentIt = new LuxuryCarRental(name, zipCode, carSize, 
         daysRented, chauffer);
         rentIt.display();
 

Whereas the object rentIt is of type LuxuryCarRental. But the class LuxuryCarRental does not have a method 'display'. Hence the error.
