I'm developing an application that will perform reading and writing of a particular txt file, which follows a pattern. I'm going to read a file, perform some cleanup on that file, and then write a new file. I put a progress bar to make it easier for the user to process. My question is to link the time of the read / write process when the progress bar progresses. I've incremented the bar using Thread, but times do not match. I was wondering if you have any way to get the exact time of the read / write process, and update the bar. Thanks!

My role is this @Guerra. This is the function where I load my file, throw some junk, choose whether to break the line or not, and rewrite the file.
JButton btnIniciar = new JButton("Iniciar");
btnIniciar.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("botão \"iniciar\" precionado...");
if (txtCaminhoArquivo.getText().trim().equals("")) {
JOptionPane.showMessageDialog(null, "Selecione um arquivo!");
} else {
try {
FileInputStream fi = new FileInputStream(arquivo);
InputStreamReader input = new InputStreamReader(fi);
BufferedReader br = new BufferedReader(input);
String linha = br.readLine();
OutputStream saida = new FileOutputStream("arquivo_formatado.txt");
OutputStreamWriter os = new OutputStreamWriter(saida);
BufferedWriter escreva = new BufferedWriter(os);
int numeroDeLinhas = 0;
do {
String novoArquivo[] = linha.split("\t");
for (int i = 0; i < novoArquivo.length; i++) {
escreva.write(novoArquivo[i] + ";");
}
// função do chekBox
if (chkquebrarLinhas.isSelected()) {
escreva.write("\r\n");
}
linha = br.readLine();
numeroDeLinhas++;
} while (linha != null);
escreva.close();
br.close();
System.out.println("Arquivo gerado com Sucesso!");
System.err.println("Numero de linhas lidas: " + numeroDeLinhas);
JOptionPane.showMessageDialog(null, "Arquivo convertido com suceso!");
} catch (Exception e2) {
// TODO: handle exception
} // fim di catch
} // fim do else
}// fim do ActionPeformed
});// fim do actionListner
As for using the progress bar, end a simple example like this:
new Thread() {
public void run() {
for (int i = 0; i < System.currentTimeMillis(); i++) {
try {
sleep(100);
barraProgresso.setValue(i);
if (barraProgresso.getValue() == 100) {
labelBarra.setText("Concluído");
JOptionPane.showMessageDialog(null, "Arquivo convertido com sucesso!");
}
} catch (InterruptedException interruptedExepcion) {
JOptionPane.showMessageDialog(null, "Erro ao Converter!");
}
}
}
}.start();
My only real question is how to link process time to bar status.
