用文件名中的外來字符打開文件

Question

我正在爲下個月的考試開發一個小型應用程序。在這個應用程序中，用戶可以上傳符合他們名字的文件。

不幸的是，在丹麥，我們有幾個外文字符（ÆØÅæøå），並且將包含這些我的代碼沒有打開的文件。

有沒有可以讓我使用這些文件名的解決方法？

這是一個打開的文件中的代碼：

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

和異常：

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

Answer 1

的代碼工作在Windows中。但是，本主題中使用的OSX OS顯然不支持這一點。

這工作得很好

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")); 

     } 

    } 

嘗試打印您從getStuderende().getKontrakt()方法

檢查它的相同文件您正在打開得到什麼。
