lol...This is actually a PHP forum.

• PS: This is not a complete solution.
• PSS: This is untested code, so don't blame me if you get banned from sites :P
• PSSS: You should program it concurrently using threads to increase efficiencies.

package com.company;

import java.io.IOException;
import java.net.*;
import java.util.*;

public class URLAccess {
    public List<String> urls;

    public static void main(String[] args) {
        URLAccess ua = new URLAccess();
        ua.run();
    }

    public URLAccess() {
        this.urls = new ArrayList<String>();
        // Read them from external XML or some other sources instead!
        this.urls.add("http://google.com");
        this.urls.add("http://alksdfjlaksjdflkajsdf.com");
    }

    public void run() {
        this.urls.forEach(this::accessUrl);
    }

    public void accessUrl(String urlString) {
        try {
            URL url = new URL(urlString);
            URLConnection urlConnection = url.openConnection();
            urlConnection.connect();
            System.out.println("Success");
        }
        catch (IOException ignored) {
            System.out.println("Failed");
