Sample code

import makingtransactions.NegativeBalanceException;
import makingtransactions.Transaction;
import makingtransactions.bankaccounts.JointAccount;
import makingtransactions.bankaccounts.SingleAccount;
import userservice.User;

public class TestZone {
	public static void main(String[] args) throws NegativeBalanceException {
		User charlie = new User("Charlie", 15, 25);
		User john = new User("John", 15, 21);

		SingleAccount singleAccount = new SingleAccount(45, charlie, "Single", "USD", 152, 23, 12);
		JointAccount jointAccount = new JointAccount(charlie, "Joint", "USD", 02, 01, 20);

		System.out.println("--- Swapping single account owners ---");

		System.out.println("Charlie's accounts: " + charlie.getBankAccounts());
		System.out.println("John's accounts: " + john.getBankAccounts());

		singleAccount.setUserHolder(john);

		System.out.println("\nSwapped holder to john:\n");
		System.out.println("User holder: " + singleAccount.getUserHolder());

		System.out.println("Charlie's accounts: " + charlie.getBankAccounts());
		System.out.println("John's accounts: " + john.getBankAccounts());

		System.out.println("--- Adding and removing joint account users ---");

		System.out.println(jointAccount.getUsers());

		jointAccount.addUser(john);
		System.out.println(jointAccount.getUsers());

		jointAccount.addUser(john);
		System.out.println(jointAccount.getUsers());

		jointAccount.removeUser(charlie);
		System.out.println(jointAccount.getUsers());

		jointAccount.removeUser(john);
		System.out.println(jointAccount.getUsers());

		System.out.println("--- TRANSACTIONS ---");

		Transaction transaction = new Transaction("Groceries", 0, 0, 12);

		System.out.println("Single account before: " + singleAccount.getBalance());

		singleAccount.addTransaction(transaction);

		System.out.println("Single account now: " + singleAccount.getBalance());
		System.out.println("Single account transactions: " + singleAccount.getTransactions());
