我正在尝试Oracle网站上的JavaFX教程[fxml tutorial](http://docs.oracle.com/javase/8/javafx/get-started-tutorial/fxml_tutorial.htm).

package fxml;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

class Main extends Application {

    public Main() {}

    @Override
    public void start(Stage stage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("welcome.fxml"));

        Scene scene = new Scene(root);

        stage.setTitle("FXML UI");
        stage.setScene(scene);
        stage.show();
    }

    public static void main(String args[]) {
        launch(args);
    }

}

这是我不断得到的例外.应用程序未显示在屏幕上.我从另一个堆栈溢出答案做了非args Main()构造函数,但它没有修复它.

Exception in Application constructor
Exception in thread "main" java.lang.RuntimeException: Unable to construct Application instance: class fxml.Main

分段错误发生在函数un()中,它返回两个数组的并集.
但这里是完整的代码以防万一.我尝试在un()中添加一些print语句,但它仍然显示Segmentation fault而没有其他内容.

我正在使用GCC.

#include <stdio.h>
#include <stdlib.h>

void input_set(int* set, int size) {
    int i;
    for(i = 0; i < size; i++) {
        scanf("%d", set+i);
        if(i != 0 && set[i] == set[i-1]) {
            printf("A set cannot have repeated values. Enter again!\n");
            i--;
        }
    }
}

void display_set(int *set, int size) {
    int i;

    printf("{ ");
    for(i = 0; i < size-1; i++)
        printf("%d, ", set[i]);
    printf("%d }\n\n", set[size-1]);
}
