运行可执行文件.jar文件崩溃/错误

Question

我是java开发新手，我正在制作一个比萨管理系统，但是当我尝试运行我的可执行文件时.jar文件加载第一页，但是当我点击一个选项时它崩溃了，给我以下错误。它说没有找到文件，但我通过文件输入流导入了我的项目文件夹中的文件，如下所示。我再次在Java程序创建新的有人可以告诉我如何解决这个问题？

public void CarryOrDeli() throws FileNotFoundException { 
    Stage option = new Stage(); 
    GridPane gp = new GridPane(); 
    gp.setPadding(new Insets(0, 100, 0, 0)); 

    for (int i = 0; i < 6; i++) { 
     gp.getColumnConstraints().add(new ColumnConstraints(165)); // column 
                    // is 
                    // wide 
    } 

    for (int i = 0; i < 7; i++) { 
     gp.getRowConstraints().add(new RowConstraints(200)); // column 1 is 
                   // // 50 
                   // wide 
    } 
    // <-------------------------------------------------------> 
    // getting images from files. 
    FileInputStream one = new FileInputStream("carryout.jpeg"); 
    FileInputStream two = new FileInputStream("delivery.jpeg"); 

    // converting to a viewable node image 
    Image c = new Image(one); 
    Image d = new Image(two); 
    ImageView carryout = new ImageView(c); 
    ImageView delivery = new ImageView(d); 

    Text title = new Text("  Chose Carryout or Delivery"); 
    title.setFill(Color.BLUE); 
    title.setStyle("-fx-font: 24 arial;"); 

    carryout.setFitWidth(100); 
    carryout.setFitHeight(100); 

    delivery.setFitWidth(100); 
    delivery.setFitHeight(100); 

    gp.add(carryout, 2, 1); 
    gp.add(delivery, 4, 1); 
    gp.add(title, 2, 0, 3, 1);

您需要在JAR档案打包你的形象，你的当前补丁源和点无处当你的编译和打包到罐子工作。

FileInputStream one = new FileInputStream("carryout.jpeg"); 
FileInputStream two = new FileInputStream("delivery.jpeg"); 

更换到

InputStream stream = this.getClass().getResourceAsStream("\carryout.jpg"); 

文件carryout.jpg必须在同一目录下的类文件present.Place它resources文件夹，当您使用标准的Java项目文件夹的布局。
