Method

voidfireSelectRow(final JTable table, final int row)
fire Select Row 
EventQueue.invokeLater(new Runnable() {
    @Override
    public void run() {
        if ((row >= 0) && (row < table.getRowCount())) {
            table.clearSelection();
            table.setRowSelectionInterval(row, row);
});
intgetSelectedModelRow(JTable table)
Transforms the selected row index in the table view to the selected index of the underlying table model (in case the results are sorted, they can be different). 
int wantedModelIdx = -1;
DefaultListSelectionModel model = (DefaultListSelectionModel) table.getSelectionModel();
int selectedView = model.getLeadSelectionIndex();
if (table.getModel().getRowCount() > selectedView && selectedView >= 0) {
    try {
        int selectedModelIdx = table.convertRowIndexToModel(selectedView);
        if (table.getModel().getRowCount() > selectedModelIdx) {
            wantedModelIdx = selectedModelIdx;
...
voidmoveRowSelection(JTable pJTable, int pRow)
move Row Selection 
Rectangle rect = pJTable.getCellRect(pRow, 0, true);
pJTable.scrollRectToVisible(rect);

voidselectClickedRow(final JTable table, final MouseEvent event)
Selects a table row depending on a mouse event. 
final int row = table.rowAtPoint(event.getPoint());
