[SOLVED] hello, java program with 2 errors, help

Hi I am trying to compile and run this file but there is two errors: here is the original assignment but I did the rest.

/* This program calculates the number of gallons of paint needed to paint a room.

Programmer:

Date: March 31, 2009

*/

import java.util.Scanner;

public class PaintersHelper {

static float DOOR_SIZE = 15.0f;

static float SMALL_WINDOW_SIZE =2.0f;

static float LARGE_WINDOW_SIZE = 5.0f;

static float SQ_FT_PER_GALLON = 375.0f;

public static void main(String[] args) {

// declare all variables to be used (I provide one to get you started.)

int gallons;

// give welcome and instructions to user

// prompt user for the room's width

// prompt user for the room's length

// prompt user for the room's height

// prompt user for the number of doors

// prompt user for the number of small windows

// prompt user for the number of large windows

// gross square feet = height * 2 * (length + width)

// subtractions is the sum of:

// number of doors * door size

// number of lgWindows * lgWindow size

// number of smWindows * smWindow size

// net square feet = gross square feet - subtractions

// gallons = netSqFt / SQ_FT_PER_GALLON rounded to the nearest gallon

// display the answer.

System.out.println("\nYou will need about " + gallons + " gallons of paint.");

} // end of method main

} // end of class PaintersHelper
