// Open an input stream which allows you to read the source file.
BufferedReader reader = new BufferedReader(new FileReader(srcFileName));

// Open an output stream which allows to write to a destnation file.
BufferedWriter writer = new BufferedWriter(new FileWriter(destFileName));

// Create a buffer of some reasonable size. The reading and writing will be done
// in chunks of that buffer size.
char[] buffer = new buffer[4096];

int bytesRead;
while ((bytesRead = reader.read(buffer, 0, buffer.length)) > 0)
{
  writer.write(buffer, 0, bytesRead);
}

// Close streams
reader.close();
writer.close();

You will also have to take care of IOException handling.
