Problem concerning parsing int from .dat input

> Monday 5/15/2006

> Buy: -1

> Sell: -->-1<--

>

> That was the input with the code. I tried many

Ok, how about this:

System.out.println("Sell: -->" + sell + "<--; length=" + sell.length());

Is length = 2?

Make a folder named whatever the current date is, and put a .dat file in there with this;
