我正在学习javafx。
我正在尝试创建路径,但是当我实例化类Path()时,我收到以下消息:“java.nio.file.Path是abstract;无法实例化”
package mapas;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.effect.BoxBlur;
import javafx.scene.paint.Color;
import javafx.scene.shape.Circle;
import javafx.scene.shape.StrokeType;
import javafx.stage.Stage;
import java.nio.file.Path;
import javax.sound.midi.Patch;
public class Mapas extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
Group root = new Group();
Group circles = new Group();
Scene scene = new Scene(root, 800, 600, Color.BLACK);
primaryStage.setScene(scene);
circles.setEffect(new BoxBlur(10, 10, 3));
primaryStage.show();
for(int i = 0; i < 30; i++){
Circle circle = new Circle(150, Color.web("white", 0.05));
circle.setStrokeType(StrokeType.OUTSIDE);
circle.setStroke(Color.web("white", 0.16));
circle.setStrokeWidth(4);
circles.getChildren().add(circle);
}
root.getChildren().add(circles);
Path path = new Path(); // <-- error
}
}
怎么了?
答案 0 :(得分:3)
您确定要import java.nio.file.Path
而不是javafx.scene.shape.Path
?????
