    The code below did not work. It compiled, but I got an exception
where I tried to instantiate a BufferedReader when I executed it:

Exception in thread "main" java.util.NoSuchElementException
    at java.util.AbstractList$Itr.next(AbstractList.java:427)
    at Test.main(Test.java:31)

    I think I don`t know the proper way to use fileIter.hasNext() to
initialize the reader.

    Anyone know what I am doing wrong? Thanks, Alan

ArrayList<File> MyFileList = new ArrayList<File> ();
. . .
MyFileList = FileList.getFileList( CurrentDirectory, translit, false,
false );
. . .
for ( Iterator<File> fileIter = MyFileList.iterator();
fileIter.hasNext(); )
{
  BufferedReader infile = new BufferedReader(new InputStreamReader(new
FileInputStream(fileIter.next().getName()),"UTF-8"));
}


The exception means that there are no more elements when you call
next(). From the code you posted I don't see a problem. Is there more
code?

You can simplify getting a BufferedReader to
  new BufferedReader(new FileReader(File f))
