file - java.io.FileNotFoundException : "C:/Users/Joe/Desktop/file.txt" (The filename, 目录名，或者卷标语法不正确)

Question

我有这个代码:

BufferedReader in = new BufferedReader
(new InputStreamReader(System.in));
System.out.print("Public Key to encrypt with: ");
String publicKeyFilename = in.readLine();
FileInputStream fis = new FileInputStream(publicKeyFilename);

当我输入文件“C:/Users/Joe/Desktop/file.txt”的目的地时，结果是这个错误:

java.io.FileNotFoundException: "C:/Users/Joe/Desktop/file.txt" (The filename, directory name, or volume label syntax is incorrect)

但是文件存在，我该怎么办？

感谢你..
