New to java,,,help needed urgently

Question

I am geeting a compile error..."cannot resolve symbol" in my main class. The program is supposed to prompt the user for five sets of data, and calculate the tax and total of the entered products and print it back to the screen, it is also supposed to calculate the cheapest and most expensive item and print them back. can someone pls shed some light on this error msg, as I cant seem to get my head around it.
import java .io.*;
import java.util.StringTokenizer;
import java.text.NumberFormat;
import java.util.Locale;
//set up a class to call on the constructors from the catalogueitem class
public class Myassg4
     private static final int MAX = 2;//sets the length to 2
     private static CatalogueItem[] prodlist ;//sets array for product list
     NumberFormat cash = NumberFormat.getCurrencyInstance(new Locale("en","AU"));
     private static void main(String[] args) throws IOException
     {//declare the variables and initialize
     double preTotal = 0.00;
     String inString;
     double maximum, lowest;
     double sum = 0.00;
     BufferedReader stdin = new BufferedReader (new
     InputStreamReader(System.in));
     prodlist = new CatalogueItem[];//sets the length (THIS IS WHERE THE PROBLEM OCCURS!!!!)
System.out.println("Enter 5 sets of data");
     //loop through the array and read the data in
     for(int i = 0;i <prodlist.length;i++)
          inString = stdin.readLine();
          //create a String Tokenizer to read the data separately
          StringTokenizer tok = new StringTokenizer(inString, ":");
prodlist[i] = new CatalogueItem(tok.nextToken(), tok.nextToken(),
Double.parseDouble(tok.nextToken()));
}//end of loop
//create a header and print the data back to the screen
System.out.println();
System.out.println("LISTING OF ALL GOODS");
System.out.println();
System.out.println("Cat\tDescription\tExTax\tTax\tIncTax");
System.out.println("___\t___________\t_____\t___\t______");
System.out.println();
for(int j = 0;j <prodlist.length;j++){
System.out.println(prodlist[j].getCatno()+"\t"+prodlist[j].getDesc()+
"\t"+prodlist[j].getPrice()+"\t"+prodlist[j].getTax()
+"\t"+prodlist[j].getIncTax());
I have errors every where the prodlist is used, I know I am not initializing it correctly but dont know what the alternatives are.

daniel here is the entire code if you do get a chance can you pls have a look at it for me thanks.
