Buddy I picked up an example comic

Manipulative.java.:

package gomes.fernando.robson;

 import java.io.BufferedReader;
 import java.io.BufferedWriter;
 import java.io.FileReader;
 import java.io.FileWriter;
 import java.io.IOException;
 import java.util.Scanner;

public class ManipuladorArquivo 
{

public static void leitor(String path) throws IOException {
    BufferedReader buffRead = new BufferedReader(new FileReader(path));
    String linha = "";
    while (true) {
        if (linha != null) {
            System.out.println(linha);

        } else
            break;
        linha = buffRead.readLine();
    }
    buffRead.close();
}

public static void escritor(String path) throws IOException {
    BufferedWriter buffWrite = new BufferedWriter(new FileWriter(path));
    String linha = "";
    Scanner in = new Scanner(System.in);
    System.out.println("Escreva algo: ");
    linha = in.nextLine();
    buffWrite.append(linha + "\n");
    buffWrite.close();
}

}

Main java.:

package gomes.fernando.robson;

import java.io.IOException;

public class Principal {

public static void main(String args[]) throws IOException {
    String path = "/tmp/file.txt";

    ManipuladorArquivo.escritor(path);
    ManipuladorArquivo.leitor(path);
}

}

Well the main class will use the Manipulative class.java which has the function to read and write the file. Good you just treat the reading with the visual part, xml ...
