Question

我正在为下个月的考试开发一个小应用程序。在此应用程序中，用户可以上传与其名称相匹配的文件。

不幸的是，在丹麦，我们有一些外国字符（ÆØÅæøå），我的代码不会打开包含这些字符的文件。

是否有允许我使用这些文件名的解决方法？

这是打开文件的代码：

Desktop.getDesktop().open(new File("kontrakt/" + getStuderende().getKontrakt()));

例外：

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: The file: kontrakt/5_Bjørnen-Bjørn-kontrakt.docx doesn't exist.

Answer 1

代码在Windows中正常运行。但是，本主题中使用的OSX OS显然不支持此功能。

这很好用

package others;

    import java.awt.Desktop;
    import java.io.File;

    public class A {

        public static void main(String[] args) throws Exception{


            Desktop.getDesktop().open(new File("c://5_Bjørnen-Bjørn-kontrakt.docx"));

        }

    }

尝试从getStuderende().getKontrakt()方法

打印您获得的内容
