sockets Getting started with sockets Create unconnected socket, try connect to it and check if connection is established

Example

 public class ConnectSocketExample {

    private int HTTP_PORT = 80;

    /**
     * example method to create unconnected socket
     * then connect to it
     * at end return connected socket
     *
     * @param httpHostName - endpoint host name fot socket connection
     * @throws IOException - if the socket is already connected or an error occurs while connecting.
     */
    protected Socket connectSocket(String httpHostName) throws IOException {
        // define local variable for socket and create unconnected socket
        Socket socket = new Socket();
        //  create iNet address for socket
        InetSocketAddress inetSocketAddress = new InetSocketAddress(httpHostName, HTTP_PORT);
        // connect socket to inet address (end point )
        socket.connect(inetSocketAddress);
        // return connected socket for later use 
        return socket;
    }
    
    /** 
     * public method for try to create connected to goole.com http port socket 
     * and with check and system out print if this try was successful
     **/
    public void createAndCheckIfConnected() {
        try {
            Socket connectedSocket = connectSocket("google.com");
            boolean connected = connectedSocket.isConnected();
            System.out.print("Socket is:" + (!connected ? " not" : "" +  " connected"));
        } catch (IOException e) {
            e.printStackTrace();
