Thread: Java error while using BufferedReader class to read a .txt document

I'm trying to write my first I/O program and I seem to have a problem with using the BufferedReader class. Every time I read in from a .txt document and then print out to a different one it prints out every other line, starting with the second line. I'm pretty sure it is not the PrintWriter's fault because I did not have a problem with printing strings I defined in the program. When I put a line space in between each line the output was the way I wanted, but the file is a dictionary file with hundreds of thousands of words so I can't possibly manually enter all those spaces. Could someone please help me with this problem? I was told something about using flush, and I set the automatic flush argument to true for the PrintWriter, which didn't seem to have any effect.

The input file was a file I used to test if it would work that contained the following:
AA
BB
CC
DD
What was printed in the output file was:
BB
DD
Here is the code:

/*Temporary program for reprinting the dictionary file.
Created on January 3, 2009*/
 
import java.io.FileReader;
import java.io.FileWriter;
import java.io.BufferedReader;
import java.io.PrintWriter;
import java.io.IOException;
 
public class SortDic
{
public static void main(String[] args) throws IOException
{
String placeHolder;
FileReader fr = new FileReader("TestFile.txt");
BufferedReader readWord = new BufferedReader(fr);
FileWriter fw = new FileWriter("TWL_Dic.txt");
PrintWriter printWord = new PrintWriter(fw, true);
 
System.out.println("Working...");
while(readWord.readLine() != null)
   {
   placeHolder = readWord.readLine();
   printWord.println(placeHolder);
   }
System.out.println("Done.");
 
readWord.close();
printWord.close();
 
}
}

Thanks for your help.

I can't believe I didn't see this. It seems so obvious now. I thought that the loop condition just verified that the first line was not null and then the read the first line again for the printing, but it makes sense that the loop condition is actually a part of the loop that executes every time. Thanks for all the help, the answer was simpler than I thought!

Thanks for your help, JavaPF. I will mark my threads when they are solved from now on.
