For example there is a table named sub_table with 3 columns ie sub_id, sub_name,class. when I select one of the rows from that table and click delete button that particular row should be deleted..

It's very simple.

• Add ActionListener on button.
• Remove selected row from the model attached to table.

Sample code: (table having 2 columns)

Object[][] data = { { "1", "Book1" }, { "2", "Book2" }, { "3", "Book3" }, 
                    { "4", "Book4" } };

String[] columnNames = { "ID", "Name" };
final DefaultTableModel model = new DefaultTableModel(data, columnNames);

final JTable table = new JTable(model);
table.setSelectionMode(javax.swing.ListSelectionModel.SINGLE_SELECTION);


JButton button = new JButton("delete");
button.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent arg0) {
        // check for selected row first
        if (table.getSelectedRow() != -1) {
            // remove selected row from the model
            model.removeRow(table.getSelectedRow());
        }
    }
});
