If the file is already existing- Try using only Reading the file. Because if you open the stream for writing to the file- The contents will get erased provided you are not trying to append the contents to the file.
Probably the OP not providing all the lines in the file. Next time it may be a good idea to bring up the text editor, find line 29, and tell us which line it is -- as it may not be the same if you don't provide all of the file.

This line has problem
The whole code:
I have a text file I want read it and show the content by byte stream
it has problem because You haven't initialized the in reference to a valid FileInputStream reference. Please note that unless you initialize the object references with valid instances/objects you cannot use those references.
