2outputStreams are meant for writing, you can read from them – sanbhat Jul 11 '13 at 14:20

close the outputstream, and open the file with the fileinputstream? – user2097804 Jul 11 '13 at 14:21

Stream is in my memory - it's ByteArrayOutputStream. then I need FileInputStream variable, of that Stream. – Jul 11 '13 at 14:22

I don't have file. I have ByteArrayOutputStream. – Jul 11 '13 at 14:23

You can create a ByteArrayInputStream with
InputStream is = new ByteArrayInputStream(bos.toByteArray());
and then read from this InputStream.
If your interface only accepts a FileInputStream then the interface is broken...
If, at all, an interface only works with files it should accept a File else it should use an InputStream.
Also if you use threads you can use PipedInputStream and PipedOutputStream directly between the threads.

I need only FileInputStream. or I have byte array (byte [] variable) and I want to read from FileInputStream – Jul 11 '13 at 14:32

2+1 for "If your interface only accepts a `FileInputStream` then the interface is broken" – Ian Roberts Jul 11 '13 at 14:47
