1. HttpURLConnection:
URL url = new URL("http://example.com");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
InputStream inputStream = connection.getInputStream();
}
2. Apache HttpClient:
CloseableHttpClient httpClient = HttpClientBuilder.create().build();
HttpGet httpGet = new HttpGet("http://example.com");
CloseableHttpResponse response = httpClient.execute(httpGet);
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode == HttpStatus.SC_OK) {
HttpEntity entity = response.getEntity();
}
3. OkHttp:
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder().url("http://example.com").build();
Response response = client.newCall(request).execute();
if (response.isSuccessful()) {
String responseData = response.body().string();
}
