I am trying to build some sort of baking program for a school assignment. Iv meet most of the requirements but i need help logging transactions done during the active process. It does not need to save the information to a text file or anything. All it needs to do is keep a temporary memory of all transactions done. Here is what I have in terms of code.
MainProgram
| code: |
import java.util.*;
public class MainProgram {
public static void main(String[] args) {
//-------------------------------------------------------------------------------------------------------------
//-------------------------------------------------------------------------------------------------------------
//-------------------------------------------------------------------------------------------------------------
Scanner scanner;
Date today;
String lineSeparator = System.getProperty("line.separator");
today = new Date(); //this initilizes the date
scanner = new Scanner(System.in); //initializes the scanner so input is possible
scanner.useDelimiter(lineSeparator);
double transAmount;
int transOption;
int transNumber;
boolean userWantsToQuit = false;
//-------------------------------------------------------------------------------------------------------------
//-------------------------------------------------------------------------------------------------------------
//-------------------------------------------------------------------------------------------------------------
//create some bank account objects
BankAccount b1 = new BankAccount("Bob ", 1001, 1000.0);
BankAccount b2 = new BankAccount("Joe ", 1002, 0.0);
BankAccount b3 = new BankAccount("Jack", 1003, 500.0);
//-------------------------------------------------------------------------------------------------------------
//-------------------------------------------------------------------------------------------------------------
//-------------------------------------------------------------------------------------------------------------
while (!userWantsToQuit){
//-------------------------------------------------------------------------------------------------------------
//-------------------------------------------------------------------------------------------------------------
//-------------------------------------------------------------------------------------------------------------
System.out.println("The Time Is: " + today);

BankAccount

| Why not make Transaction a class of its own rather than just a method? That way you can store all your Transactions into a Collection. |

|
| so you make a Singleton class for Transactions, and as Hellblazer suggests - have all the new data be pushed onto a Collection. |
