Thread: About deleting rows from table model.

How to delete row from the table model without selecting it? The user will just input a number which matches the data from the table?

example:

ID | Name | Year |
----------------------------------
1 | Derpina D. | 3rd year |
----------------------------------
2 | Zsannen M. | 2nd Year |
----------------------------------

*The program will ask for an existing ID that will be deleted.

ENTER ID #: 1

*Once the user entered a valid ID, all the information about ID #1 will be deleted.

ID | Name | Year |
----------------------------------
2 | Zsannen M. | 2nd Year |
----------------------------------


*The information is saved to a .txt file. Whenever i input ID number, the information about the entered ID will be deleted on the .txt file. The problem is, only in the GUI, the table, is not being deleted.

*When deleting, you don't select the row. Instead, you have to input the ID #.


Would someone help me with this? Thanks in return.
Badly confused here. I've tried some codes but it doesn't work out.

THIS IS MY CODE BELOW:

int select = Integer.valueOf(data.toString());
int nRow = tableModel.getRowCount();
Object[] tableData = new Object[nRow];
 
for (int i = 0 ; i < nRow ; i++){
tableData[i] = tableModel.getValueAt(i, i);
//tableModel.removeRow();
}

Have a look at the javadoc for the DefaultTableModel, it has the needed delete methods. Then you have to create your JTable with your own DefaultTableModel and use that.
