Java Netbeans将查询结果提取到JLabel中

Question

我有JFrame form要求用户插入例如他的名字，然后它会显示他拥有的所有房屋的地址（用户可能拥有多个房屋）。

然而，由于我不知道查询会产生多少结果，我创建了一个vector类型的函数并将数据存储到其中，然后返回向量。在JFrame表单中，我正在做这样的事情。

Vector<String> data = User.getHouse(userName.getText());
        if (data.isEmpty()) {
        JOptionPane.showMessageDialog(null, "No Houses were found!");
        }
        else {
           for(int i=0; i<data.size(); i++)
              {
                 System.out.println(data.elementAt(i));
                 houses.setText(data.elementAt(i));
                 houses2.setText(data.elementAt(i+1));
                }
            }

功能代码：

  public static Vector<String> getHouse(String playerName) throws SQLException, ClassNotFoundException {
    Connection con = DBConnect.getConnection();
    PreparedStatement getId = con.prepareStatement("SELECT Player_Id from PLAYERS WHERE Name = ?");
    getId.setString(1, playerName);
    ResultSet y = getId.executeQuery();
    if(y.next())
    {
        id = y.getString("Player_id");
        System.out.println("playerID => " + id);
    }
    System.out.println("playerName => " + playerName);

    PreparedStatement s = con.prepareStatement("SELECT House_Name FROM HOUSES WHERE Player_Id = ?");
    s.setString(1, id);
    System.out.println("getHouse => Query");
    ResultSet x = s.executeQuery();
    Vector<String> data = new Vector<String>();
    while(x.next())
    {
        data.addElement(x.getString("House_Name"));
    }
    return data;
}

（查询返回2行）。如何使用查询结果正确设置JLabel text？
