Почему не записывает?? Во втором файле пуста???

public static void main(String[] args) throws Exception{
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        String firstFileName = reader.readLine();
        String secondFileName = reader.readLine();
        reader.close();
        FileReader fileReader = new FileReader(firstFileName);
        FileWriter fileWriter = new FileWriter(secondFileName);

        int i = 1;
        while (fileReader.ready()){
            int data = fileReader.read();
            if(i % 2 == 0)
                fileWriter.write(data);
            i++;
        }
        fileReader.close();
        fileWriter.close();
    }

while (fileReader.ready()){
    int data = fileReader.read();
    fileWriter.write(data);
}

if(i % 2 == 0)
               fileWriter.write(data);

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String firstFileName = "SomeFile";
String secondFileName = "OtherFile";
reader.close();
