When scraping dates from a website using Java, the SimpleDateFormat class is commonly used for parsing and formatting dates. Below is an example demonstrating how to scrape dates from a webpage and parse them using SimpleDateFormat. Additionally, you can use a library like Jsoup for HTML parsing.
Make sure to replace the URL, HTML parsing logic, and date format patterns with your specific requirements.
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import java.io.IOException;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class DateScrapingExample {
public static void main(String[] args) {
String url = "https://example.com"; // Replace with the URL of the webpage containing dates
try {
// Fetch HTML content using Jsoup
Document document = Jsoup.connect(url).get();
// Replace the following logic with the actual HTML parsing logic for dates
Element dateElement = document.selectFirst(".date-selector"); // Replace with the appropriate selector
String dateString = dateElement.text(); // Get the text content of the element
// Parse the date using SimpleDateFormat
SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date parsedDate = inputFormat.parse(dateString);
// Format the date for display
SimpleDateFormat outputFormat = new SimpleDateFormat("EEE, MMM d, yyyy 'at' h:mm a");
String formattedDate = outputFormat.format(parsedDate);
// Print the formatted date
System.out.println("Scraped Date: " + formattedDate);
} catch (IOException | ParseException e) {
e.printStackTrace();
}
}
}
In this example:
SimpleDateFormat
class is used to parse the scraped date string into a Date
object using the specified input format.SimpleDateFormat
is used to format the date into a more readable output format.Note: Make sure to handle exceptions appropriately, and adjust the date format patterns according to the actual format used on the webpage.
UDP (User Datagram Protocol) is a transport layer protocol that provides a simple and fast way to send data over a network. Unlike TCP, UDP does not establish a connection between the sender and receiver before sending data. Instead, UDP uses a connectionless communication model, where each datagram (data packet) is sent independently.
Here's how UDP works:
1. The sender application prepares the data to be sent and wraps it in a UDP datagram. This datagram contains the data, the source IP address, the destination IP address, and a checksum for error detection.
2. The sender application sends the UDP datagram to the network layer, which then forwards it to the appropriate network interface for transmission.
3. The datagram is transmitted over the network as a single, self-contained packet. There is no guarantee that the datagram will reach its destination, as UDP does not provide any error correction or retransmission mechanisms.
4. The receiving application listens for incoming UDP datagrams on a specific port. When a datagram arrives, the network layer forwards it to the appropriate application.
5. The receiving application processes the datagram, extracts the data, and handles any errors detected by the checksum.
It's important to note that UDP does not establish a connection between the sender and receiver. This means that there is no handshake or acknowledgment of receipt, and the sender does not know if the datagram was successfully delivered. UDP is often used for applications that prioritize speed over reliability, such as video streaming, online gaming, and VoIP (Voice over Internet Protocol).
To send a UDP request to a STUN server in C++, you can use the following example code. This example uses the boost::asio library for handling asynchronous I/O operations and boost::beast for handling UDP communication. Make sure you have the Boost library installed on your system before running this code.
#include

namespace http = boost::beast::http;
using tcp = boost::asio::ip::tcp;
using udp = boost::asio::ip::udp;
int main(int argc, char* argv[]) {
if (argc != 3) {
std::cerr << "Usage: stun_udp_request " << std::endl;
return EXIT_FAILURE;
}
boost::asio::io_context ioc;
udp::resolver resolver(ioc);
udp::resolver::results_type results = resolver.resolve(argv[1], argv[2]);
if (results.empty()) {
std::cerr << "Cannot resolve: " << argv[1] << ":" << argv[2] << std::endl;
return EXIT_FAILURE;
}
udp::socket udp_socket(ioc);
udp_socket.connect(results.begin()->endpoint());
// Prepare the STUN Binding Request
std::string stun_request =
"BINDING_REQUEST\r\n"
"MIXED_RELAY\r\n"
"USER-AGENT: STUN-UDP-Example\r\n"
"\r\n";
// Send the STUN Binding Request
boost::system::error_code ignored_error;
udp_socket.send_to(boost::asio::buffer(stun_request), results.begin()->endpoint(), 0, ignored_error);
// Receive the STUN Binding Response
boost::beast::flat_buffer buffer;
http::response response;
udp_socket.receive_message(buffer, response);
// Print the STUN Binding Response
std::cout << "STUN Binding Response:\n";
std::cout << response.what() << std::endl;
return EXIT_SUCCESS;
}
To compile the example, you can use the following command:
g++ -std=c++17 -o stun_udp_request stun_udp_request.cpp -lboost_system -lboost_as
To set up a proxy on your computer, you need to go through a simple procedure. If we're talking about Windows 10, you'll first need to open the "Settings" application and the "Network and Internet" section. Here, after opening the "Proxy Server" tab, find the column "Manual proxy server setup" just to the right and move the switch to the "On" position. Enter the IP address and the proxy port in the specified fields and click "Save".
The first thing you need to do to use a proxy in your browser is to make the necessary settings. In Google Chrome browser, go to "Network" and then find and click on "Change proxy settings". In the "Internet properties" window that opens, go to "Connection" and click on the "Network settings" button at the bottom. When a new window opens, check the "Use proxy server for local connections" box and the "Do not use proxy server for local addresses" box. Enter the proxy port and IP address in the corresponding fields, close the window and click "OK".
