根据数据库中的ResultSet，用每个按钮单击不同的按钮填充HBox

Question

我有应聘者数据库。在主页上，我应该显示一些信息，在单击名称时，应打开另一个包含更多信息的窗口，但是单击名称时，我会报错。我尝试将名称放入标签冷杉中，但由于标签不可点击，因此切换到按钮。在添加setOnAction之前，我的代码一直有效，所以我认为这是问题所在

我的问题：有没有一种方法可以创建未指定数量的按钮，每个按钮都会在while循环中向方法发送不同的ID

这是我的代码：

ResultSet rs = stmt.executeQuery("SELECT id,ime,prezime,glavna_tehnologija,znanje from kandidat ");

while (rs.next()) {
HBox hBox = new HBox(40);

Button btn = new Button(rs.getString("ime") + " " + rs.getString("prezime"));

btn.setOnAction(e->{           
try {
new PrikazInformacijaKandidataProzor().pregled(rs.getInt("id"));
} catch (SQLException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
            }

});

hBox.getChildren().addAll(new Label(Integer.toString(rs.getInt("id"))),btn, new Label(rs.getString("glavna_tehnologija")), new Label(rs.getString("znanje")));
    kandidatiV.getChildren().add(hBox);
        }

我的PrikazInformacijaKandidataProzor()具有方法pregled(int id)，该方法应该获取候选人的ID，并基于数据库信息的显示，但是当我单击按钮中显示的任何名称时，我都会出错
