How to get file size in different units ?

Get file size

File file = new File("c:\\geniusLogo.jpg");

double bytes = file.length();

// length() method returns in bytes, so convert it to other unit

double kilobytes = (bytes / 1024);

double megabytes = (kilobytes / 1024);

double gigabytes = (megabytes / 1024);

double terabytes = (gigabytes / 1024);

double petabytes = (terabytes / 1024);

double exabytes  = (petabytes / 1024);

double zettabytes = (exabytes / 1024);

double yottabytes = (zettabytes / 1024);

System.out.println(bytes + " bytes");

System.out.println(kilobytes + " kb");

System.out.println(megabytes + " mb");

System.out.println(gigabytes + " gb");

System.out.println(terabytes + " tb");

System.out.println(petabytes + " petabytes");

System.out.println(exabytes  + " exabytes");

System.out.println(zettabytes + " zettabytes");

System.out.println(yottabytes + " yottabytes");
