Error(39,1),can not find symbol method write(java.io.bufferedReader)

pls help

Thank you

There error is reporting this line:

Java Code:

outputChannel.write(in);

outputChannel is an instance of FileChannel. Check javadoc of FileChannel here. It does not have a write method which has a BufferedReader parameter as reported in this error. You should send an instance of ByteBuffer to that method.

Dear levent

once i change my coding like below it gives error message.
Error ByteBuffer is abstarct class and u cant create instance Bytebuffer.

I dont know much about these topics.

pls help

coding

ByteBuffer xc=new ByteBuffer(new InputStreamReader(yc.getInputStream()));

Thank you

It seems that you can not create a bytebuffer like that. Read the javadoc please, it says you can create a bytebuffer allocating or wrapping.

I recommend you to use the downloadPage() method in the following example:

Java Tips - How to create a Search Crawler in Java

It shows a clear way of doing this. And since you will need to create some ind of crawler to download all pages on a web site, other methods might help you too.

downloadPage method in that example downloads a web page and returns it as a string. In your case, you can save the returned string to the disk or create your own method based on that example.
