Help on ByteArrayInputStream

[K.Z.Zamli]

Dear all

I am having a problem to save from ByteArrayInputStream to file..
Refer to the following excerpt of code:

...............
DatagramPacket receivePacket = new
DatagramPacket (buffer, buffer.length);
socket.receive(receivePacket);

System.out.println("Packet received");
System.out.println("\nFrom host" + receivePacket.getAddress() +
"\nHost port" + receivePacket.getPort() +
"\nLength" + receivePacket.getLength()); // +
// "Word" + s);

ByteArrayInputStream bais = new

ByteArrayInputStream(receivePacket.getData(),
0,receivePacket.getLength());


The question is how can I save the bais (ByteArrayInputStream) as a
binary file ?

Any help is really appreciated. Thanks in advanced.

ByteArrayInputStream bais = new ByteArrayInputStream(receivePacket.getData(),
0,receivePacket.getLength());

If you just want to save the datagram contents, there's no need for
the ByteArrayInputStream here at all.

Use DatagramPacket.getData() to get the data from the packet as a byte
array. Use a FileOutputStream to write the contents of the byte array
to a file.

The whole point of a ByteArrayInputStream is to get you a byte[].

Now your problem is how to write that byte[] to a file.
The file I/O Amanuensis will show you dozens of ways to do that.
