import java.security.cert.Certificate;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.SSLSocketFactory;

public class Main {
  public static void main(String[] argv) throws Exception {
    int port = 443;
    String hostname = "hostname";
    SSLSocketFactory factory = HttpsURLConnection.getDefaultSSLSocketFactory();
    SSLSocket socket = (SSLSocket) factory.createSocket(hostname, port);

    socket.startHandshake();

    // Retrieve the server's certificate chain
    Certificate[] serverCerts = socket.getSession().getPeerCertificates();

    socket.close();
