// In JDK7
List<String> lines = Files.readAllLines(Paths.get("a.txt"), Charset.forName("utf8"));

Files.write(Paths.get("b.txt"), lines, Charset.forName("utf8"));

// for big file
Path path = Paths.get(aFileName);
try (BufferedReader reader = Files.newBufferedReader(path, ENCODING)){
  String line = null;
  while ((line = reader.readLine()) != null) {

  }
}

try (BufferedWriter writer = Files.newBufferedWriter(path, ENCODING)){
  for(String line : aLines){
    writer.write(line);
    writer.newLine();
  }
}

// Or use PrintWriter
PrintWriter out = new PrintWriter("filename.txt");
out.println(text);
