Checking strings for empty
<p>Very tired this morning so if this is obvious then thats my excuse !!!</p>

<p>i am using a buffered reader to read through a csv file - but i dont want to add any empty spaces, as in</p>

<p>" "</p>

<p>the problem is - when i read the line i am checking if the string length is > 0, if so then add, however the string " " is of length 4 - even tho its empty </p>

<p>is there a better check i can do</p>

<p>thanks </p>
