java download file from url

To download a file from a URL in Java, you can use the URL and URLConnection classes from the java.net package to open a connection to the file, and the InputStream and OutputStream classes from the java.io package to read and write the file.

Here's an example of how to download a file from a URL in Java:

import java.io.*;
import java.net.*;

public class FileDownloader {
    public static void main(String[] args) throws IOException {
        // Define the URL of the file to download
        String fileUrl = "https://example.com/files/myfile.txt";

        // Open a connection to the URL
        URL url = new URL(fileUrl);
        URLConnection connection = url.openConnection();

        // Set the user agent to pretend to be a web browser
        connection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3");

        // Connect to the URL
        connection.connect();

        // Get the input stream to read the file
        InputStream inputStream = connection.getInputStream();

        // Create a file output stream to save the file
        FileOutputStream outputStream = new FileOutputStream("myfile.txt");

        // Create a buffer to improve download speed
        byte[] buffer = new byte[4096];
        int bytesRead;

        // Read the file from the input stream and write it to the output stream
        while ((bytesRead = inputStream.read(buffer)) != -1)
