import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;

import java.util.Scanner;
public class HtmlTags {
public static void main(String args[]) {
try {
Scanner reader = new Scanner(System.in);
System.out.println("Enter a website name :");
String websiteAddress = reader.nextLine();
if (websiteAddress != null) {
URL url = new URL(websiteAddress);
// Read all the text returned by the server
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String str;
while ((str = in.readLine()) != null) {
str = in.readLine().toString();
if (str != null) {
System.out.println(str);
// str is one line of text; readLine() strips the newline character(s)
} else {
System.out.println("No output returned: Make sure the web address is correct");
}
}
in.close();
} else {
System.out.println("Please do enter a valid website address!!!!!");
}
reader.close();
} catch (MalformedURLException e) {
System.out.println("Not a valid URL provided: Please enter a valid one");
