bufferedreader question, please help.

[javalearner2]

hi

I'm using bufferedreader to read a file now.
How can I say, if the next line is null (without jumping to the next line ), then do something. (say, print helloworld)

It's like, i want to have a function "boolean hasNextLine()". Please provide me the code and syntax if you can.
Thank you.

You can't.
Here's the API for BufferedReader.
All you have (on top of the standard read() methods) is a readLine() method.
It doesn't have a way to test whether there's a line.
If you think about it a while you'll see that that would not be possible in most cases where the BufferedReader would be used to wrap a stream.

If you accept a restriction (a maximum line length), it can be done:

br.mark(maxlineLength);
boolean hasLine= br.readLine() != null;
br.reset();

But I find this whole thing a sily academic exercise with no practical use ...

kind regards,

Jos
