title: Splitting text file without reading it
body: <p>Is there any method so that I can split a text file in java without reading it?</p>
  
  <p>I want to process a large text file in GB's, so I want to split file in small parts and apply thread over each file and combine result for it.  </p>
  
  <p>As I will be reading it for small parts then splitting a file by reading it won't make any sense as I will have to read same file for twice and it will degrade my performance.</p>
