java.io.IOException: Input/output error at last line of a file

Question

I am facing issue while processing last line of a file.

java.io.IOException: Input/output error

    at java.io.FileInputStream.readBytes(Native Method)

    at java.io.FileInputStream.read(FileInputStream.java:272)

    at sun.nio.cs.StreamDecoder.readBytes(StreamDecoder.java:283)

    at sun.nio.cs.StreamDecoder.implRead(StreamDecoder.java:325)

    at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:177)

    at java.io.InputStreamReader.read(InputStreamReader.java:184)

    at java.io.BufferedReader.fill(BufferedReader.java:154)

    at java.io.BufferedReader.readLine(BufferedReader.java:317)

    at java.io.BufferedReader.readLine(BufferedReader.java:382)

Everything is working fine, but while reading the last line getting an error at br.readLine().

BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file))) ;
String line = null;
 while((line = br.readLine()) != null){}

are you using windows or linux?? it could be the line ending format — Alejandro Teixeira Muñoz, Apr 19 '18 at 11:40
@XtremeBaumer some string. consider "jsvdh#1236 25373, 1637 2727, ; 2627, , ,#" — Nitin Nandankar, Apr 19 '18 at 11:42
can you write "file xxxxx" (where xxx is yur file name)?? and, can you try it after doing "dos2unix yourfile" ?? Check this answer -> https://stackoverflow.com/a/82743/3617531 — Alejandro Teixeira Muñoz, Apr 19 '18 at 11:44
@XtremeBaumer not with every files, but whenever it occurs, it gets reflected for every files. — Nitin Nandankar, Apr 19 '18 at 11:45
@AlejandroTeixeiraMuñoz `BufferedReader.readLine()` respects all linux, DOS/WIN and MacOS line ends, so no need to tranform using dos2unix. — diginoise, Apr 19 '18 at 11:47
@NitinNandankar how big is the file, or how long is the last line? Is this file open by any other process, for reading or writing? — diginoise, Apr 19 '18 at 11:48
@diginoise each file is has 12 lines and each line is has more than 10000 words — Nitin Nandankar, Apr 19 '18 at 11:50
but the same file is getting processed successfully on someones system — Nitin Nandankar, Apr 19 '18 at 11:56
@NitinNandankar, could you please print e.getMessage() on the catch clause ??? — Alejandro Teixeira Muñoz, Apr 19 '18 at 12:01
@AlejandroTeixeiraMuñoz you can find stack trace in the above question — Nitin Nandankar, Apr 19 '18 at 12:17

could you maybe be running out of memory?¿ did you tried to execute the java with , for example: `java -Xms256m -Xmx2048m` ? — Alejandro Teixeira Muñoz, Apr 19 '18 at 12:45
Hey @NitinNandankar How is all? Did you finally managed how to solve it? Did you find new clues? — Alejandro Teixeira Muñoz, Apr 20 '18 at 09:23
@AlejandroTeixeiraMuñoz yes. Its hardware issue. Because of frequent connect-disconnect of hard-disk, IO error occurred. — Nitin Nandankar, Apr 20 '18 at 09:26
hehehhe It seemed to be something like that. The memory issue should have been reported (I was thinking on it yesterday when driving home). Happy to see you solved it!! . Plz, detail the solution in the answer and close it!! :) thanks a lot! — Alejandro Teixeira Muñoz, Apr 20 '18 at 09:28
@AlejandroTeixeiraMuñoz i have tried it by reading files from a pendrive. At the start of reading lines from a file, i disconnected my pendirve and again reconnected it will the system. The solution is " i have changed my hardware." — Nitin Nandankar, Apr 20 '18 at 18:52
