Java Homework

Hey guys, I know this is homework and if you don't feel like helping that's fine. I'm just getting stumped by this code and I'm getting a little desperate.


import java.util.*;
import java.text.DecimalFormat;

public class WeatherStation {    

    static int HowMany = 0;
    static Scanner input = new Scanner(System.in);
    private static double[] Weather, Celsius = new double[HowMany];
    private static double WeatherFSum = 0, WeatherCSum = 0;
    private static double FMean = WeatherFSum / HowMany;
    private static double CMean = WeatherCSum / HowMany;
    public static String Command = "";
   
    private static class WeatherData {
        public String StationDesignation;
        public double Temperature;
       
        public WeatherData(String ID, double Temp) {
            StationDesignation = ID;
            Temperature = Temp;
        }
        };
       
        public static void main(String[] args) {
                System.out.print("What is your command? ");
                Command = input.nextLine();
                if(Command.equals("Fill"))
                    Fill();
                else if(Command.equals("Display"))
                    Display();
            }
       
        public static void Fill() {
            int X;
            String Item;
            double Entry;
            System.out.print("Hello!\n\nHow many weather stations will we be checking on? ");
            HowMany = input.nextInt();
            WeatherData[] Weather = new WeatherData[HowMany];
            for(X = 0; X < HowMany ; X++) {
               
            System.out.println("Please enter the name for WeatherStation" + X + ": ");
            Item = input.next();
            if(Item.equals("Stop")) break;
            System.out.println("Please enter temp in fahreinheit: " );
            Entry = input.nextDouble();
            WeatherData[X] Weather = new WeatherData(Item, Entry);
            }
        }




I know that the last line with WeatherData[X] and all that other stuff is complete crap. I get errors upon errors with that. But I'm trying to work out how to make an array of this datatype that I created, and then assign values from the keyboard to instances of that datatype.

Can anyone help? I've googled and searched around but none of the explanations seem to click.
