            }
        });
    }
}

as you can see in the program I wrote a simple block that displays a console ouput of the selected rows, Im trying to highlight a multiple selected row in a search by a JTextField, for example I entered 20, it will highlight all the rows that has that value, but I can only Highlight the last one in the search selection, I dont know how to implement .getSelectedRows() in a right way.. please I need help with this while im trying to resolve it on my own..

[camickr]

table.setRowSelectionInterval(row, row);

That resets the selection. I believe you need to use:

table.addRowSelectionInterval(row, row);
