New to Java

Hi all,

I read a text file line by line and I want to skip the empty line, which has no string at all(only space).Here is the code I use but it doesn't work.
I wonder if I use the right regular expression.

Thank you,

String line;
while((line=inputFile.readLine()!=null) &&line.matches("\\w+"))
{
   //do something here
}
