Answer 1

I used this method for my ServerUtil.

    public static boolean isOnline() {
    boolean b = true;
    try{
        InetSocketAddress sa = new InetSocketAddress("SERVER_IP_ADDRESS", PORT);
        Socket ss = new Socket();
        ss.connect(sa, 1);
        ss.close();
    }catch(Exception e) {
        b = false;
    }
    return b;
}
