Java NIO advantages if there is a single client and complete object read is required
// Reading from socket
private SomeObject readObject() throws IOException, ClassNotFoundException {
    Object object = oiStream.readObject();
    if (object != null && object instanceof SomeObject) {
        SomeObject someObject = (SomeObject) object;
        return someObject;
    }
    return null;
}

    // Writing to socket
    public void writeToSocket(SomeObject someObject) throws IOException {
    if (isSocketOpen()) {
        ooStream.writeObject(someObject);
        ooStream.flush();
    }
}
