oh,god ,i am sure there is no mistake in my mthhod on case sensitive.
i just copy it from a class to another class .and it go wrong and the
IDE
said that in javax.swing.JFileChooser can't applied to (<anonymous

| java.io.fileFilter>).

Well, duh! First of all, there is no such type as 'java.io.fileFilter'.

In the second place, did you even check the Javadocs for
<http://java.sun.com/javase/6/docs/api/javax/swing/JFileChooser.html#setFileFilter(javax.swing.filechooser.FileFilter)>
?

Had you done so, you would have seen that the method is not even defined to
take a java.io.FileFilter, so that wouldn't work either.
