Comment obtenir du contenu URL en Java

Dans cet exemple Java, nous vous montrons comment obtenir le contenu d'une page à partir de l'URL «example.com» et l'enregistrer dans un lecteur de fichier local, nommé «test.html». 

package com.example;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;

public class GetURLContent {
    public static void main(String[] args) {

        URL url;

        try {
            // get URL content
            url = new URL("http://www.example.com");
            URLConnection conn = url.openConnection();

            // open the stream and put it into BufferedReader
            BufferedReader br = new BufferedReader(
                               new InputStreamReader(conn.getInputStream()));

            String inputLine;

            //save to this filename
            String fileName = "/users/example/test.html";
            File file = new File(fileName);

            if (!file.exists()) {
                file.createNewFile();
            }

            //use FileWriter to write file
            FileWriter fw = new FileWriter(file.getAbsoluteFile());
            BufferedWriter bw = new BufferedWriter(fw);

            while ((inputLine = br.readLine()) != null) {
                bw.write(inputLine);
            }

            bw.close();
            br.close();

            System.out.println("Done");

        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}
