JavaFX InputMismatchException-掃描程序中的標簽

Question

問題會在那里導致我想要從文本文件中制作標簽，然后將其放入VBOX中，並且我得到inputmismatchexception，並且它不制作新對象

VBox vertikalBox = new VBox();
try (Scanner s = new Scanner("rebricek.txt")) {
        while (s.hasNext()) {
            //InputMismatchException 
            vertikalBox.getChildren().addAll(new Label(""+ s.nextInt() + " " + s.next() + " " + s.nextInt()));
            s.nextLine();
        }


    } catch (Throwable t) {
        // inputmismatchexception - PROBLEM
        // this is for NoSuchElementException
        System.err.println("Vyskytla sa chyba pri praci zo suborom");
    }

文件內容：

3 nikto 0
4 nikto 0
5 nikto 0
6 nikto 0
7 nikto 0

Answer 1

您的掃描儀正在讀取字符串“ rebrickek.txt”而不是文件

File file = new File("rebricek.txt");

if(file.exist())
{
    Scanner s = new Scanner(file);
    .
    .
    .
}
else
{
    System.out.println("The file does note exist!");
}
