public void EncryptFile (String fileName) {FileInputStream fis=null; File File=null;try {file=new file (fileName); fis = new FileInputStream (file); System.out.println (File.length ()); System.out.println (Fis.available ());}          catch (FileNotFoundException e) {e.printstacktrace ();} catch (IOException e) {e.printstacktrace ();} }
File.length (); fis.available (); Is the way to get the file size, but the file.length () return type is a long fis.available () The return type is int, and reading the file size is inaccurate if the maximum value of the integer setting is read.
