    Default Making JTable Non-Editable

    I want to make non-editable to table.
    I am taking data using DbUtils. I can take the data but I can not make non-editabale.
    try {
                String SQL = "SELECT * FROM tblmalzemeler ";
                preparedStatement = baglanti.prepareStatement(SQL);
                resultSet = preparedStatement.executeQuery();
                        tableMalzeme.setModel(DbUtils.resultSetToTableModel(resultSet)
     
                        );
     
            } catch (Exception e) {
            }


    Probably I should use isCellEditable method but I can not make it. How can I put following code in setModel method.

        boolean[] canEdit = new boolean [] {
            false, false, false, false, false, false, false, false
        };
    public boolean isCellEditable(int row, int col) {  // iscelleditable function  
        return false;
      }

    You can explicitly override a class that implements TableModel. Or you can use anonymous classes.

    class Foo implements TableModel {
    // Implement all the methods here
    }
    What's so difficult? Btw, I would recommend you to extend one of the default implementations of TableModel rather then inventing your own.

    If I don't use "DbUtils.resultSetToTableModel" I can make non-editable.
    How can I make non-editabale using " jTable2.setModel(DbUtils.resultSetToTableModel(res ultSet)"

    jTable2.setModel(new javax.swing.table.DefaultTableModel(
        new Object [][] {
            {null, null, null, null},
            {null, null, null, null},
            {null, null, null, null},
            {null, null, null, null},
            {null, null, null, null},
            {null, null, null, null}
        },
        new String [] {
            "Title 1", "Title 2", "Title 3", "Title 4"
        }
    ) {
        boolean[] canEdit = new boolean [] {
            false, false, false, false
        };
     
        public boolean isCellEditable(int rowIndex, int columnIndex) {
            return canEdit [columnIndex];
        }
    });

    How can I declare "isCellEditable" in this method
    tableMalzeme.setModel(DbUtils.resultSetToTableModel(resultSet)
            );

    Well, you can use, for example, this and this methods to convert your table model to other model. Perhaps, you might want to create a separate method for conversion.
