How to check if the next line is empty with a BufferedWriter

Question

I'm using a buffered writer to write words in a text file, which works. But the writer starts at a new line every time, so you get all the words underneath each other with output.nextLine(); Can I check if a line is empty with an if statement so it wont print an empty line?

Here's the code:

BufferedWriter output = new BufferedWriter(new FileWriter("products.txt", true));
                    output.newLine();
                    output.append(s+" : "+price+" Euro");
                    output.close();

Because right now my txt file has an empty line at the top if I dont have text there.

You should edit your title to remove references to a buffered *reader*. It's also not very clear what you are asking. — Duncan Jones, Mar 11 '15 at 09:55
Your question is really unclear. Can you explain in more detail what your problem is? Perhaps some examples would help. — Duncan Jones, Mar 11 '15 at 10:00

To write to a file line by line without printing empty lines, change your code to the following:

BufferedWriter output = new BufferedWriter(new FileWriter("products.txt", true));
output.append(s+" : "+price+" Euro\n");
output.close();

@Bas I recommend you create your `BufferedWriter` as specified in [this answer](http://stackoverflow.com/a/6998929/474189) so that you can specify a charset. – Duncan Jones Mar 11 '15 at 10:08
