NoSuchElementException

[Alan]

I call a method of mine, getFileList, which returns an ArrayList of
files and is stored in MyFileList. I know how to iterate through the
ArrayList, but how do I open the file for reading?

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))

for ( Iterator<File> fileIter = MyFileList.iterator();
fileIter.hasNext(); )

if myFileList is a collection of Files, (note lower case m), you can
use the new for:each iteration syntax

for (File f : myFileList )
{

}

What do you do with a File? see

for sample code.

I was using the next() method twice!

I was using the next() method twice!

That will do it!
