im new to java and i have a question regarding Synchronized.

i have the following code for writing to network (simple implementation for now):

public void networkSendData(byte[] data){

    try {

        out.write(data);
        out.flush();

    } catch (IOException e) {


    }
}

i was wondering if there is a need for block level Synchronized here as im am writing the whole data at once. or is there a chance for race condition? i ask because the data to write is coming for multiple sources.

thank you.
