Question Details:
CODE

//class declarations
class Account{
private int        accNum;
private double     balance;
  Transaction trans;

Account(int a, double b, String f, String l){
  accNum = a;
  balance = b;
   Transaction[]trans= new Transaction[10];
}

class Transaction{
private int accNum;
private String date;
   Transaction(int a, String d){
  accNum = a;
  date = d;
   }

Problem
I have two files, "accounts.txt" and "transaction.txt", I am trying to read the transaction data from the transaction file into the main Account.
//Code
Transaction[index].trans[i] = new Transaction(in.nextInt(), in.next());
index = position returned by binarysearch
//error : Transaction cannot be located, what might the problem be?
