ByteArrayInputStream and ByteArrayOutputStream

[new_2_java]

Hi all,

I am getting the content of a source object which is returned as ByteArrayInputStream, and then I am assigning to a target object, which accepts input as ByteArrayOutputStream. Can someone please suggest as how can I convert ByteArrayInputStream to ByteArrayOutputStream, so that I can assigne it to my target object.

Here's my code:

Code:

ByteArrayInputStream content = source_object.getContent(); 

// how can I set the content of my source_object to the content of my target_object

target_object.setContent(<it accepts a ByteArrayOutputStream>)

Please advise...


Thanks,

Not sure what you mean by

other than to copy from one to the other.
Your request doesn't make sense. If setContent() wants an output stream, I would assume that the target_object class wants somewhere to WRITE something. An input stream is where there is something to be READ.

So, do I need to read the InputStream into a file and then write it to an OutputStream?

It all depends on your application.
You can read an inputstream and write it to an outputstream without using a file.

Can you give me an example, please.

while((aByte = bais.read()) != -1)
baos.write(aByte);

Thanks, I will try that.
