ok lets start fresh. This is my orignal program:
...Code:import java.util.Scanner; public class ChargeAccount1 { static int[] validChargeAccountNumbers = { 5658845, 4520125, 7895122, 8777541, 8451277, 1302850, 8080152, 4562555, 5552012, 5050552, 7825877, 1250255, 1005231, 6545231, 3852085, 7576651, 7881200, 4581002Leave a comment:

so based on number = [] its not reading the file right?Leave a comment:
-
yeah its the first...Have it memorized now lol. I used the System.out.prin tln("number = " + number); got error number symbol not found. then i used the
//code to read the file and store each account into the vector validChargeAcco untNumbers
{
Scanner s = new Scanner("valid_ accounts.txt");
while(s.hasNext Int())
validChargeAcco untNumbers.add( s.nextInt());...Leave a comment:
