How to check if the response of a server returns (200 OK) in java? [closed]

The verification can be done using Android's own REST APIs, making a GET call from a URL and waiting for a Response, from that Response you make the logic on top of the Status Code you receive.

Another alternative is to use the Java API itself to check, but it will be limited to the package API java.net

Ex:

public int getStatusCode(String urlPath) {
    try {
        URL url = new URL(urlPath); // http://www.seusite.com.br
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.connect();
        return conn.getResponseCode();
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
}
