How to do so that when I select the checkbox of one row and select another checkbox from another row it is stored in a variable and when I click the send button it is sent to another table to be validated.

This is the creation code of the table:

tbDocTransferir.setModel(new DefaultTableModel(
            new Object[][] {
            },
            new String[] {
                "C. Costo", "Cod. SD", "Tipo de Archivo", "N\u00B0 Doc.", "Permanencia", "Tipo de Nivel de Archivo", "Per. Ret.", "Solicitar"
            }
        ) {
            @SuppressWarnings("rawtypes")
            Class[] columnTypes = new Class[] {
                Object.class, Object.class, Object.class, Object.class, Object.class, Object.class, Object.class, Boolean.class
            };
            @SuppressWarnings({ "unchecked", "rawtypes" })
            public Class getColumnClass(int columnIndex) {
                return columnTypes[columnIndex];
            }
            boolean[] columnEditables = new boolean[] {
                false, false, false, false, false, false, false, true
            };
            public boolean isCellEditable(int row, int column) {
                return columnEditables[column];
            }
        });
        tbDocTransferir.getColumnModel().getColumn(0).setPreferredWidth(93);
        tbDocTransferir.getColumnModel().getColumn(1).setPreferredWidth(87);
        tbDocTransferir.getColumnModel().getColumn(2).setPreferredWidth(125);
        tbDocTransferir.getColumnModel().getColumn(4).setPreferredWidth(95);
        tbDocTransferir.getColumnModel().getColumn(5).setPreferredWidth(150);
        tbDocTransferir.getColumnModel().getColumn(6).setPreferredWidth(92);
        tbDocTransferir.getColumnModel().getColumn(7).setPreferredWidth(61);
        tbDocTransferir.setDefaultRenderer(Object.class, new Mirender());
        scrollPane.setViewportView(tbDocTransferir);
        tbDocTransferir.setRowSelectionAllowed(true);
        tbDocTransferir.setColumnSelectionAllowed(false);

This code is so that the information that is in the database is listed in the table:

void ListarDocumento(String centroCosto){
            ArrayList<ServicioArchivisticoDTO> doc = x.ListarDocumento(centroCosto);
            DefaultTableModel model = (DefaultTableModel) tbDocTransferir.getModel();
            model.setRowCount(0);
            for (ServicioArchivisticoDTO s : doc){
                Object fila[] = {s.getCentroCosto().getC_t_costo(), s.getSerieDocumental().getC_c_sd(), s.getTipoArchivo().getC_t_tipo_archivo(),
                                    s.getArchivo().getC_t_doc(), s.getSerieDocumental().getN_i_tiempo_retencion()+" años", s.getNivelArchivo().getC_t_nivel_archivo(),
                                    s.getPeriodo_retencion()};
                model.addRow(fila);
            }
        }

I have not used Swing in Java for a long time, but if I remember correctly, you have to implement a listener in the checkbox in order to retrieve the object you are labeling. From there you could add it to a list and fill the other table. Greetings!

Using the TableModelListener function, you could do the following, using getRowCount() to get the total number of rows in your table and getValueAt() which will get the value in a given position.

//obtenemos el modelos de tu tabla y le agregamos el listener
tbDocTransferir.getModel().addTableModelListener(new checkBoxListener());

public class checkBoxListener implements TableModelListener {

   public void tableChanged(TableModelEvent e) {
    int fila = e.getFirstRow();
    int columna = e.getColumn();
    //verifica si la columna es de tipo boolean
    if (columna == BOOLEAN_COLUMN) {
        /*
            obtenemos el modelo de la tabla
            este te servira al igual para obtener los valores de tu tabla,
            dependiendo de la fila y columna que desees tomar.
        */
        TableModel model = (TableModel) e.getSource();
        Boolean checked = (Boolean) model.getValueAt(fila, columna);
        //verifica si esta seleccionada
        if (checked) {
            //aqui haces la insercion del registro a una nueva tabla
        }
   }
}
