title: How to launch a PDF File using PDFBox
body: <p>I want to get the time elapsed while opening a pdf file . I am not able to find a way to do it using PDFBox.I  created a PDDocument in my java program and want to use some API to launch the PDF file through my code .I am unable to find out which PDFBox  API that would serve the purpose.
  So it would be helpful if i can get some info on that.</p>
  
  <p>Thanks.
