我得到了以下代码,并且有这个错误(我试图保持代码尽可能短,忽略getColumnCount等函数只是构造函数):

下面的代码用于通过SQLite语句在Swing中创建JTable,我需要复选框的布尔值(是的,我知道我必须编辑/添加一个函数,但我想保持代码尽可能小).

码:

package view;

import java.sql.ResultSet;
import java.sql.SQLException;

import javax.swing.table.AbstractTableModel;

import controller.Database;

class Test extends AbstractTableModel {
        Database db = new Database();
        ResultSet rs;

        private String[] columnNames = {"Vorname", "Nachname", "E-Mail", "Anrede", "Jahrgang", "Ablösung", "Scheibe", "Waffe", "Gruppe", "Verpflegung", "Aktiv"};
        Object[][] data;

        public Test(){
            int result = 0;
            try {
                rs = db.stat.executeQuery("select count(*) as schuetzencount from schuetze;");
                result = Integer.parseInt(rs.getString("schuetzencount"));
                data = new String[result][11];
            } catch (SQLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            try {
                rs …
