Receive byte[] using ByteArrayInputStream from a socket

Question

Here is the code but got error:

bin = new ByteArrayInputStream(socket.getInputStream());

Is it possible to receive byte[] usin

Answer 1

You can't get an instance of ByteArrayInputStream by reading directly from socket.
You require to read first and find byte content.
Then use it to create an instance of ByteArrayInputStream.

InputStream inputStream = socket.getInputStream();  

// read from the stream  
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
byte[] content = new byte[ 2048 ];  
int bytesRead = -1;  
while( ( bytesRead = inputStream.read( content ) ) != -1 ) {  
    baos.write( content, 0, bytesRead );  
} // while  

Now, as you have baos in hand, I don't think you still need a bais instance.
But, to make it complete,
you can generate byte array input stream as below

ByteArrayInputStream bais = new ByteArrayInputStream( baos.toByteArray() );
