Answer 1

void newMethod() throws Exception {
     // Reading from a flat file
     String data;     
     BufferedReader br = new BufferedReader(new FileReader("c:\filename1.txt"));
     while ((data = br.readLine()) != null) {
          System.out.println(data);
     // Writing to a flat file
     BufferedWriter bw = new BufferedWriter(new FileWriter("c:\filename2.txt"));
     bw.write("sample data");
     // After writing the data close the file
     bw.close();
}
