Hey guys ! Need help ! Can not get my code to run from my nodelist. When i run it referencing my array it works, however when I try to reference my nodelist, it does not work please help!:

package zipcode;

import java.io.File; import java.io.FileNotFoundException; import java.util.Scanner;

public class ZipCodeDriver { public static void main(String[] args) { //file contening the data that will be loaded into the array String filename = "zipcodes.txt";

// Load data try { Scanner infile = new Scanner(new File(filename)); ZipCodeList1 myZipCodelist = new ZipCodeList1(); ZipCode c; while(infile.hasNext()){ c = new ZipCode(); c.setZipcode(infile.nextLine()); c.setTown(infile.nextLine()); c.setState(infile.nextLine()); myZipCodelist.add(c); } infile.close(); System.out.println("Loaded " + myZipCodelist.getSize() + " zip codes"); // Search for the data String search = ""; Scanner keyboard = new Scanner(System.in); while(true){ System.out.print("Hello, please enter zip code to search (type done to stop): "); search = keyboard.next(); if(search.equalsIgnoreCase("done")) break; c = myZipCodelist.find(search); if(c == null) System.out.println("Sorry but the zip code entered was not found"); else System.out.println("Found " + search + ": [" + c + "]"); } // In case we don''t find the data } catch (FileNotFoundException e) { System.out.println(e.getMessage()); } }

}
