Query InterNIC server's whois

Last example show Java example using WhoisClient class to query whois. Alternatively, we can query InterNIC server's whois without WhoisClient class.

package javawhois;

    private final static String WHOIS_HOST = "whois.internic.net";
    private final static int WHOIS_PORT = 43;

    public static void main(String[] args) {
        int c;
        Socket socket = null; 

        String query = "=" + WHO + "\r\n";
        byte buf[] = query.getBytes();
        
        try {
            socket = new Socket(WHOIS_HOST, WHOIS_PORT);
            InputStream in = socket.getInputStream();
            OutputStream out = socket.getOutputStream();

            out.flush();
            while ((c = in.read()) != -1) {

            if(socket != null){
                try {
