Problems with Array

I'm doing a facial recognition system, and all that's missing is for me to finish everything. I have the following code:

for (int i = 0; i < facesDetectadas.size(); i++) {
                                Rect dadosFace = facesDetectadas.get(i);
                                rectangle(imagemCamera, dadosFace, new Scalar(255, 255, 0, 0), 2, i, i);
                                Mat faceCapturada = new Mat(imagemCinza, dadosFace);
                                opencv_imgproc.resize(faceCapturada, faceCapturada, new Size(160, 160));

                                IntPointer rotulo = new IntPointer(1);
                                DoublePointer confianca = new DoublePointer(1);
                                reconhecedor.predict(faceCapturada, rotulo, confianca);
                                int predicao = rotulo.get(0);
                                String nome;
                                if (predicao == -1) {
                                    nome = "Desconhecido";
                                } else {
                                    nome = pessoas[predicao] + " - " + confianca.get(0);
                                    campoid.setText(String.valueOf(predicao));
                                    rec();
                                }
                                int x = Math.max(dadosFace.tl().x() - 10, 0);
                                int y = Math.max(dadosFace.tl().y() - 10, 0);
                                putText(imagemCamera, nome, new Point(x, y), FONT_HERSHEY_PLAIN, 1.7, new Scalar(0, 255, 0, 2));
                            }

And above, I have in the "rec" method I have the same array:

Follow the rec method:

private void rec() {
    SwingWorker worker = new SwingWorker() {
        @Override
        protected Object doInBackground() throws Exception {
            conecta.conexao();
            try {
                String SQL = "SELECT * FROM reconhecer where id=" + campoid.getText() + "";
                conecta.executaSQL(SQL);

                while (conecta.rs.next()) {
                    camponome.setText(conecta.rs.getString(1));
                    campoidade.setText(conecta.rs.getString(2));
                    campoemail.setText(conecta.rs.getString(3));
                    campobloco.setText(conecta.rs.getString(5));
                    campoapto.setText(conecta.rs.getString(6));
                    campocondominio.setText(conecta.rs.getString(7));
                    System.out.println("Pessoa idêntificada como: " + conecta.rs.getString(1));
                    System.out.println("---------------");

                    Array identificacao = conecta.rs.getArray(2);
                    String[] pessoas = (String[]) identificacao.getArray();

                    for (int i = 0; i < pessoas.length; i++) {
                        System.out.println(pessoas[i]);
                    }
                    System.out.println("");

                }

            } catch (Exception ex) {
            }
            conecta.desconecta();
            return null;
        }
    };
    worker.execute();
}

Reason for doing this separately: I made a swing worker, and this makes it easy not to crash the application.

My problem and my question: My pessoas where if is, does not recognize pessoas that is in rec , how can I make pessoas visible to everything? I tried to use global but it does not work either.
