Unwanted Linebreaks While Amalgamating Text Files

Question

Hello. I have written a program that adds text files together line by line. However, it adds a linebreak after
each file and this makes the composite file unusable for my purposes. How do I prevent this? Here is some of the code. Thanks for any suggestions anyone has.
for (int lists=0;lists<10;lists++)
try
boolean append = true;
FileReader reading = new FileReader("C:/My Documents/Molecules/" + list[lists]);
BufferedReader reads = new BufferedReader(reading);
FileWriter writing = new FileWriter("C:/My Documents/Molecule Data/total.sdf",append);
BufferedWriter writes = new BufferedWriter(writing);
boolean eof = false;
while(!eof)
String line = reads.readLine();
if (line == null)
eof = true;
else
writes.write(line);
writes.newLine();
reads.close();
writes.close();
}

First of all...the term is "concantenation"...not amalgamation. Second, you need a change in your logic...the program is working just as you designed it. If you don't want that extra line between files, then you have to add logic that says, "If I am not at the end of my current file, then add that new line, if I am at the end of my file, SKIP doing that..."
