我试图创建一个目录，但似乎每次都失败了？我已经检查过，这不是一个权限问题太，我有充分的权限写入该目录。提前谢谢。
代码如下：

private void writeTextFile(String v){
    try{

        String yearString = convertInteger(yearInt);
        String monthString = convertInteger(month);
        String fileName = refernce.getText();
        File fileDir = new File("C:\\Program Files\\Sure Important\\Report Cards\\" + yearString + "\\" + monthString);
        File filePath = new File(fileDir + "\\"+ fileName + ".txt");
        writeDir(fileDir);
        // Create file 
        FileWriter fstream = new FileWriter(filePath);
        try (BufferedWriter out = new BufferedWriter(fstream)) {
            out.write(v);
        }
    }catch (Exception e){//Catch exception if any
    System.err.println("Error: " + e.getMessage());
    }
}

private void writeDir(File f){
    try{
         if(f.mkdir()) { 
             System.out.println("Directory Created");
        } else {
        System.out.println("Directory is not created");
        }
    } catch(Exception e){
        e.printStackTrace();
    }
}

public static String convertInteger(int i) {
    return Integer.toString(i);
}

Calendar cal = new GregorianCalendar();
public int month = cal.get(Calendar.MONTH);
public int yearInt = cal.get(Calendar.YEAR);

以下是输出：

Directory is not created
Error: C:\Program Files\Sure Important\Report Cards\2012\7\4532.txt (The system cannot find the path specified)
