java the system can not find the file specified
java
Solution
We need to see the method `getFileName()` to be sure, but based on the error message and the method name, I suspect the problem is just that this method returns only the name of the file, removing the path info, so that the file is, indeed, not found.
Problem
I used Java to copy file but it appeared a exception (the system can not find the file specified). The codes are ``` public static void copyFile(String sourceFile, String destFile){ try { InputStream in = new FileInputStream(sourceFile); OutputStream os = new FileOutputStream(destFile); byte[] buffer = new byte[1024]; int count; while ((count = in.read(buffer)) > 0) { os.write(buffer, 0, count); } in.close(); os.close(); } catch (IOException e) { e.printStackTrace(); } } ``` The test codes ``` public static void main(String[] args) { String name = getFileName("D:/z/temp.txt"); String target = "D:/tem.txt"; copyFile(name, target); } ``` the exception is `java.io.FileNotFoundException: temp.txt(the system can not find the file specified)` - The file 'temp.txt' is existence. - The path is right no problem. I guess that is the problem of Permissions. who can come up with the answer thanks!
