arquivo = File.separator;
JFileChooser fc = new JFileChooser(new File(arquivo));
fc.showOpenDialog(rootPane);
fc.getSelectedFile();
File selFile = fc.getSelectedFile();
BufferedReader br;
try {
br = new BufferedReader(new FileReader(selFile));
String linha;
while (br.readLine() != null) {
linha = br.readLine();
p = linha.substring(0, 12);
//System.out.println(p);
d = linha.substring(12, 18);
//System.out.println(d);
h = linha.substring(18, 22);
//System.out.println(h);
r = linha.substring(22, 29);
//System.out.println(r);
s = linha.substring(29, 46);
//System.out.println(s);
String query = "insert into COLETA (n_pis, data,hora,n_relogio,n_serial) values('" + p.toString() + "','" + d.toString() + "','" + h.toString() + "','" + r.toString() + "','" + s.toString() + "')";
