プログラムの実行中にJavaFXでFXMLコードに混乱するエラーが発生しました。命名
まず1：
javaFxでTARGETINVOCATIONEXCEPTIONを解決するには？
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.*?>
<?import javafx.geometry.*?>
<?import javafx.scene.control.*?>

第二のファイル名は次のとおりです：含まれていFXMLDocumentController.java：次のコードが含まれていF2XML.fxml
私は3つのファイルを持っている
package javafxapplication5;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.RadioButton;
public class FXMLDocumentController implements Initializable {
@FXML
RadioButton Male;
@FXML
RadioButton Female;
@FXML
Button OK;
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
@FXML
public void BClickedActionHandler() {
System.out.println("Hello");
}
}
第3のものは、JavaFXApplication5.javaです。これは含まれています。私は次のコードで苦しんでいたプログラム実行している場合
package javafxapplication5;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;
public class JavaFXApplication5 extends Application {
@Override
public void start(Stage stage) throws Exception {
Parent root = null;
Scene scene = null;
FXMLLoader loader = new FXMLLoader(getClass().getResource("F2XML.fxml"));
loader.setController(new FXMLDocumentController());
Pane mainPane = loader.load();
scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
