不在根目录中创建文件

Question

I am getting this error

Exception in thread "main" java.io.IOException: Access is denied at java.io.WinNTFileSystem.createFileExclusively(Native Method) at java.io.File.createNewFile(Unknown Source)

here is the code, I get that exception after I hit the createNewFile line..

    `


    //ELSE Creating the new file
    String fileName =  userName + ".usr";
    File f = new File("C:/", fileName);
    f.createNewFile(); }`

Answer 1

Try to create the file yourself. Most new windows os prevent writing to root c without elevated permissions. If you cant create it manually without special permissions same goes to your code.

Answer 2

createNewFile() method throws IOException . You should handle the exception.
