Question

我想要做的是点击按钮从当前选定行获取数据，然后返回。然而，它现在返回的东西似乎是packagename+ classname+ randomnumbers和字母。

的格式

simple.UserDetails@3f59ec1e
simple.UserDetails@210337a8

选择另一行时，随机数字和字母会发生变化。我尝试使用线程作为示例。
Getting selected item from a JavaFX TableView。我想知道如何达到我想要的结果。并且，如果可能的话，也可以将数据保存在变量中。

我使用的方法：

  @FXML
    public void getRow() {
        UserDetails row = tableview.getSelectionModel().getSelectedItem();
        System.out.println(row);
    }

Answer 1

你需要说一下像row.someMethodorVariableInUserDetails这样的东西您尝试返回的内容是在UserDetails类中

从here

查看此示例

Person person = taview.getSelectionModel().getSelectedItem();
System.out.println(person.getName());

在这个例子中，他们不得不说person.somemethod（）。在这种情况下，person.getName（）;

javafx getselecteditem返回意外输出
