if you use

((DefaultTableModel)table.getModel()).removeRow(i);

, the total row count will be changed. so you have to modify the count value:

C#

int b = table.getRowCount();
            System.out.println("row count" + b);

            for (int i = 0; i <b;) {

                try
                {

                String str = (String) table.getModel().getValueAt(i, 3);
                String str1 = (String) table.getModel().getValueAt(i, 5);
                if (!(str1 == null)) {
                    ((DefaultTableModel)table.getModel()).removeRow(i);
                    b -= 1; // minus 1 if remove 1 row; not need to increase i
                    table.repaint();
                    System.out.println("remove row no is"+i);
}

                }
                else {
                   i++;
                }
                catch(ArrayIndexOutOfBoundsException e)
                {System.out.println("array index out of bound exception"+e);
                }

            }

after ony day i have got this solution
<pre lang="cs">public class TableDataDelete implements ActionListener
    {
        public void actionPerformed(ActionEvent ee) {
            int count=0;
            // int a = table.getColumnCount();
            if(table.getCellEditor() != null)
            {
                int count1=0;
                table.getCellEditor().stopCellEditing();
            int b = table.getRowCount();
            System.out.println("row count" + b);
            DefaultTableModel model = (DefaultTableModel)table.getModel();
            for (int i = 0; i < model.getRowCount(); i++) {

                try
                {
                     if(table.getCellEditor(i, 5) != null)
                    {

                System.out.println("hit count is "+count1);
                count1++;
                String str1 = (String) table.getModel().getValueAt(i, 5);
            System.out.println("second value"+model.getValueAt(i,5));
if (!(str1 == null)) {

//                  ((DefaultTableModel)table.getModel()).removeRow(i);
                    model.removeRow(i);
                     i--;
                    table.repaint();
                    System.out.println("remove row no is"+i);
}
                }

                }
                catch(ArrayIndexOutOfBoundsException e)
                {
                    System.out.println("array index out of bound exception"+e);
                }

            }
        }
}
    }
