Hi Ramakrishna there is an error in you syntax. You are not supposed to pass you file or string in arguments to InputStreamReader instead a Stream reader
for example

Without using any other library you can convert String to InputStream and then finally read with the help of BufferedReader.

Erm ... so what do you want to do? Read or write?

Why don't you show us your code (just the relevant bits please), and exactly where you're having problems.

I don't understand the point of reading the String with a BufferedReader. You already know how to write a String to a file, so why not just write your very big HTML String to the file directly?

If you really really want to read a String, you can use a java.io.StringReader. The only reason I can think why anyone might actually need that is if they're using some library that expects a Reader rather than a String. Like perhaps if you wanted to use the readLine() method of BufferedReader (though there are other ways to do the same thing). That's not the case here, so it seems pointless. But you can do it if you want. The BufferedReader is also pointless in this case - the whole String content is already in memory; you're not gaining any speed by putting it in.

Thanks All,

I converted that into inputstream and then read from reader.

@Paul Clapham That sounds easy, But I'm not getting.

If all you want to do is write the HTML to a file, then why are you trying to read from the string with a BufferedReader? Just write the string to a file directly. No need to do complicated things with trying to read from the string.
