结果集已用完

Question

第二次显示ResultSet已用尽我调用此方法。第一次没有错误。在obj[i][j] = rs.getString(1);

显示错误

public static void createTableModel(ResultSet rs) {

    try {
        rs.first();
        while(rs.next()) {
            count++;
        }
        String [][] obj;
        obj = new String [count][3];
        rs.first();
            for (int i=0; i<count; i++) {
                  for (int j=0; j < 3; j++) {
                    if(j == 0) {  
                        obj[i][j] = rs.getString(1);
                    }
                    else if(j == 1) {
                        obj[i][j] = Integer.toString(rs.getInt(2));
                    }
                    else if(j == 2) {
                        obj[i][j] = rs.getString(6);
                    }
                  }
                  rs.next();
                }
        GlobalVariables.table1 = new DefaultTableModel(obj,
        new String [] {
            "Name", "Age", "License No"
        }
    );
}
    catch (Exception e) {
        e.printStackTrace();
    }
}

我将结果集转换为列表＆gt;

List<ArrayList<String>> result = new ArrayList<>();
                do{
                ArrayList<String> row = new ArrayList<>(6);
                int i = 1;
                while (i <= 6) {
                    row.add(GlobalVariables.data3.getString(i++));
                }
                result.add(row);
                }while (GlobalVariables.data3.next());

它解决了这个问题。我仍然不知道为什么它显示错误的结果集。
