Race Conditions

• When threads share a common object, they can conflict with each other
• Sample program: multiple threads manipulate a bank account
  Here is the run method of DepositRunnable:

  public void run()
  {
     try
     {
        for (int i = 1; i <= count; i++)
        {
           account.deposit(amount);
           Thread.sleep(DELAY);
        }
     }
     catch (InterruptedException exception)
     {
     }
  }

• The WithdrawRunnable class is similar
