Parsing is the collection of all information. Accordingly, parsing a site is copying all of its source code as presented. You can use it to edit the site further or to analyze it for security purposes.

In the "Settings" of any Android smartphone there is a "VPN" item. And there you can manually specify the parameters of the proxy, through which the connection to the Internet will be made. There, some of the programs also import ready-made scripts for proxy connections.

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:

• We use the Jsoup library to fetch the HTML content from the specified URL.
• We assume there is an HTML element with a class name of "date-selector" containing the date text. Adjust the selector based on the structure of the webpage you are scraping.
• The SimpleDateFormat class is used to parse the scraped date string into a Date object using the specified input format.
• Another 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.

The maximum size of an RTP (Real-time Transport Protocol) packet when transmitted over TCP/UDP protocol depends on the payload size and the addition of RTP header information.

RTP is a transport protocol specifically designed for real-time applications like audio and video streaming. It is typically used in conjunction with UDP or TCP, as it does not provide its own transport layer.

RTP packets consist of two parts:

1. Payload: This is the actual data being transmitted, which can be audio, video, or other real-time data. The payload size is determined by the application or codec being used.

2. Header: The RTP header contains metadata required for the proper processing and synchronization of the payload. The header has a fixed size of 12 bytes. The maximum size of an RTP packet can be calculated by adding the payload size and the fixed header size:

Maximum RTP packet size = Payload size + 12 bytes (RTP header)

The payload size depends on the application or codec being used. For example, if you're using an audio codec that generates 100-byte audio frames, the maximum RTP packet size would be:

Maximum RTP packet size = 100 bytes (payload) + 12 bytes (RTP header) = 112 bytes

In the case of video codecs, the payload size can be significantly larger, depending on the video resolution, compression, and frame rate.

When RTP is used over TCP or UDP, the maximum size of the RTP packet is limited by the maximum payload size supported by the underlying transport protocol. For TCP, the maximum segment size (MSS) is determined by the MTU (Maximum Transmission Unit) of the network and the TCP header size. For UDP, the maximum packet size is limited by the MTU of the network and the UDP header size.

In summary, the maximum size of an RTP packet when transmitted over TCP/UDP protocol depends on the payload size and the addition of RTP header information, as well as the underlying transport protocol's limitations.

Regular Windows functionality has a minimum of settings for proxies. Therefore, it is recommended to use third-party applications for this purpose. For example, Proxy Switcher or Proxifier. There you can not only set the server characteristics but also, for example, create a folder for packets of traffic that are transmitted through the local network.
