How to get the Web Page’s Source Code?

In order to do it, you can do it as it is shown:

package com.mx.development;


import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.net.URL;

import java.net.URLConnection;


public class URLConnectionReader {

public static void main(String[] args) throws Exception {

URLConnection yc = oracle.openConnection();

BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream()));

String inputLine;

while ((inputLine = in.readLine()) != null)
