  @Override ... !!! 'ActionPerformed (ActionEvent e) {Zero if (e.getSource () == btnSave) {(I int = 0; I & lt; retunTable.getRowCount (); i ++) {Boolean chked = Boolean.valueOf ( RetunTable.getValueAt (i, 4) .toString ()); String Datacol 1 = Rettabletable.get Value (i, 1) .toString (); If (chked) {JOptionPane.showMessageDialog (empty, datacol 1); ColVaules.add (dataCol1); Returnbook (); Default table model DM = (default table model) retunTable.getModel (); }}}}}  

Try it out if you already have class getColumnClass ( ) of the model, then toString () There are no need for your trying to do what should be overridden. getValueAt () should return an artist-worthy boolean object, in addition to which if you are going to loop and are dynamically removing rows in the loop , You need to keep in mind that the line number of the model will be reduced with the removal of each of the lines, even if it will need to be i - each row is removed See examples below.
