How about something like this:

import java.io.*;

public class Copier {
  public static void main(String[] args) {
    try {
      BufferedReader in = new BufferedReader
                              (new FileReader("file1.txt"));
      PrintWriter out = new PrintWriter(new FileWriter("file2.txt"));
      String line = null;
      while ((line = in.readLine()) != null) {
        out.write(line);
      }
      out.close();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}

as readLine() strips the line terminators as it goes, and write()
doesn't add them.
