If i remove the row it will throws ArrayIndexoutofBoundException.
in my project executed means one gui open in that gui listed the some string. In here we can add the more string via Add Button on popup Button
Here what i need is i have to hide the particular string. That string is placed on 1st row.
i need to hide the string from end user.
now u hope understand.

You can use the JTable row filtering support in order to hide certain rows without deleting them from the model. Also see this: How can I filter rows in a JTable?

You can eliminate rows in the table by calling the removeRow() method. If you want to just hide it instead of elimintaing it you need to customize the JTable's model to meet your specs on what to display.
http://docs.oracle.com/javase/tutorial/uiswing/components/table.html

using DefaultTableModel with JTable you should be able to use model.removeRow(int row) function to remove A row from JTable. There is no way to hide a row based on index as much as i know. However, If you need to hide and re-show mechanism you need to save the row prior to delete it and Save the removedRow in a ArrayList to re-use them.. Something as follows:
List<Vector>deletedRows = new ArrayList<>();
Vector removingRow = (Vector) model.getDataVector().get(5);
deletedRows.add(removingRow);
model.removeRow(5);

Get index of dynamic checkbox in java

I have dynamic checkbox in jtable , I do it by this code
TableColumn tcolumnas = jTable1.getColumnModel().getColumn(3);
tcolumnas.setCellRenderer(jTable1.getDefaultRenderer(Boolean.class));
tcolumnas.setCellEditor(jTable1.getDefaultEditor(Boolean.class));
and I want if I check one of them I want to know the index of check box.
Hearing for your suggestion

UPDATE :
the solution is veeery simple as here
Java Getting JTable Value (Per row)

You can add a TableModelListener to the TableModel. An event will be fired any time the data in a cell is changed.

How to restrain checking single checkbox in multiple columns in Jtable

I am trying to implement a Jtable which includes three check-box tables like this:
Can you tell me how to set a single selection group of checkboxes which only allows 1 selected check-box in a single row at any time?

I know of nothing out-of-the-box for doing this. I´d have a TableModelListener check these columns every time a change is made and call setValueAt on the checkboxes as needed.

Disable particular rows of a JTable

I would like to "grey out" particular rows of a JTable so that they may not be selected by any means. The other rows should still be selectable. How do I accomplish this?

You can either override JTable.changeSelection() to deselect the offending row whenever it's selected, or provide your table with a custom ListSelectionModel where you override setSelectionInterval(), addSelectionInterval(), etc. to prevent the row from being selected in the first place.

You will want to create a custom TableCellRenderer, one that will display "disabled" information greyed out. Read the Swing Table Tutorial for more on how to create these renderers, especially the section, Concepts: Editors and Renderers.

Create a temporary TableModel which has only the rows that you want to select. After the selection made and when you want to revert, change back to original TableModel

adding JComboBox to a jTable with specific data per row

I am trying to add a JComboBox to the last column of my JTable. The JComboBox isn't for editing purposes but for traversing the JTable itself. Each row can have 0-many elements that need to go in the JComboBox and when a value is selected from the box I need to scroll to a different row in the JTable.
All the research I have done points me specifically to editors and renderers with the down fall being that data in the JComboBox is set per column so that a user can select a value for the cell in the row. Where as I need values that are specific to the row.
So my question is, has anyone tried to do this before? and Can you point me to some good information on how to do this? or even better could you describe how you did this?

1/ simple example here, your job is only to move (hold) TableCellEditor to the last row in the TableView,
2/ if JComboBox's Item changed then search in TableModel for TableRow (if every TableColumns ends with JComboBox)
3/ then call myTable.changeSelection(row, column, false, false);
4/ possible fauls implemented and used RowSorter, RowFilter, then you have to get int row from TableView and convert that to the TableModel by using
int modelRow = convertRowIndexToModel(row);
