Java – How to get source code of websites

Source code is property of website's owner. We cannot get source of PHP, JSP, ASP or perl. This is dynamic programming code and executed on the web server by related language. We can get source code of website of HTML, JavaScript, CSS.

This code is executed on client machine. We easily get this code by java URL object and class.

<%@ page language="java" import="java.net.*,java.io.*" %>
<%
 URL yahoo = new URL("http://in.yahoo.com/");
 URLConnection yc = yahoo.openConnection();
 BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream()));
 String inputLine;
 StringBuilder sb=new StringBuilder();
