无法从JavaFX中的FileChooser路径加载图像

Question

我已经将onAction方法添加到FileChooser的图像视图中。单击后，应将ImageView图像替换为新选择的图像。

package sample;

import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.stage.FileChooser;
import javafx.stage.FileChooser.ExtensionFilter;
import java.io.File;

public class Controller {
    public ImageView image;
    public void event() {
        ExtensionFilter imageFilter = new FileChooser.ExtensionFilter("Image Files", "*.jpg", "*.jpeg", "*.png", "*.gif");
        FileChooser fc = new FileChooser();
        fc.getExtensionFilters().add(imageFilter);
        File file = fc.showOpenDialog(Main.thisStage);
        setImage(file.getAbsolutePath());
    }
    private void setImage(String url) {
        image.setImage(new Image(url));
    }
}

但我正面临此错误：
