JAVA - '未安装提供程序“C”'错误无法修复:(

Question

我有一个问题，我遇到了这个错误并且无法修复它:(任何帮助请？

 try {
         Path p3 = Paths.get(URI.create("C:/Users/User/Desktop")); //This line is causing the error
         writeToExcell(jTable,p3);
     } catch (IOException ex) {
         Logger.getLogger(AutomaticReOrder.class.getName()).log(Level.SEVERE, null, ex);
     }

错误是这样的：

`Exception in thread "AWT-EventQueue-0" java.nio.file.FileSystemNotFoundException: Provider "C" not installed
    at java.nio.file.Paths.get(Paths.java:147)
    at Products.AutomaticReOrder.jButton1ActionPerformed(AutomaticReOrder.java:130)
    at Products.AutomaticReOrder.access$000(AutomaticReOrder.java:36)
    at Products.AutomaticReOrder$2.actionPerformed(AutomaticReOrder.java:96)
    at .......

URI.create 方法需要一个 RFC 2396 格式的字符串。请看here. 字符串"C:/Users/User/Desktop" 无效。
