title: Cant identify blank string value
body: <p>Hey I got a problem in my app currently im parsing values from an website whit Jsoup and then parsing them to floats but the problem is that some of those values are something like this : " " and I can't identify those ! And I got a bug saying can't pass those values to float ! How can I make that when I got that value from website I pass it to a string whit the value "N/A" or something ? I have tried something like this :</p>
  
  <pre><code>   if(valueFromwebsite.equals(" ")){
  valueFromwebsite = "N/A"
  }
  </code></pre>
  
  <p>But its not working !</p>
  
  <p>This is the website : <a href="http://www.dges.gov.pt/guias/detcursopi.asp?codc=9186&amp;code=3043" rel="nofollow noreferrer">http://www.dges.gov.pt/guias/detcursopi.asp?codc=9186&amp;code=3043</a></p>
  
  <p>And the value that im parsing is the last ".tvag" that in this case is " " but normally would be "115,5"</p>
