私はこれについて多くのサイトを閲覧しており、いくつかの異なることを試しましたが、困惑しています. 助けていただければ幸いです。チェックボックスが選択されている (true) かどうかをチェックする条件が機能していますが、model.removeRow(row) を実行するとすぐにこのエラーが発生します。

public class ExpenditurePanel extends JPanel implements TableModelListener{

private static final long serialVersionUID = 1L;
private static TableModel1 model;
private JTable table;

public ExpenditurePanel() {
    model = new TableModel1();
    table = new JTable(model);
    table.setBorder(new BevelBorder(BevelBorder.LOWERED, null, null, null, null));
    table.setRowSelectionAllowed(false);
    table.setFillsViewportHeight(true);
    table.setCellSelectionEnabled(true);
    table.setColumnSelectionAllowed(false);

    model.addColumn("Name");
    model.addColumn("Week");
    model.addColumn("Fortnight");
    model.addColumn("Month");
    model.addColumn("Year");
    model.addColumn("Remove");

    Object[] default1 = {"Accomodation","","","","",false};
    Object[] default2 = {"Food","","","","",false};

    model.addRow(default1);
    model.addRow(default2);

    model.addTableModelListener(this);

    this.add(new JScrollPane(table));
    table.setRowSorter(null);

}

public static TableModel1 getModel(){
    return model;
}

@Override
public void tableChanged(TableModelEvent e) {
    int row = e.getFirstRow();
    int column = e.getColumn();
    model = (TableModel1) e.getSource();
    String columnName = model.getColumnName(column);
    Object data = model.getValueAt(row, column);

    if(model.getValueAt(row,column) == Boolean.TRUE){
        System.out.println("Condition working");

        //this part keeps giving me error.
        model.removeRow(row);
    }
}
}

これはそれが捨てるものです：

そうするだけです：

clsController.getTable().setSortable( false );
model.removeRow( selectedModelRow );
clsController.getTable().setSortable( true );

そしてそれは動作します！

イベントタイプを確認できます。そうすることで、追加と削除の tableChanged メソッドの内容をスキップできます。

public void tableChanged(TableModelEvent e) {
    int type = e.getType();

    if (type != TableModelEvent.DELETE && type != TableModelEvent.INSERT) {

    // operation only for update

    }
}
