Using File.listFiles with FileNameExtensionFilter


java file filter java-6

The FileNameExtensionFilter class is intended for Swing to be used in a JFileChooser.

Try using a FilenameFilter instead. For example:

File dir = new File("/users/blah/dirname");File[] files = dir.listFiles(new FilenameFilter() {    public boolean accept(File dir, String name) {        return name.toLowerCase().endsWith(".txt");    }});

java file filter java-6

One-liner in java 8 syntax: 

pdfTestDir.listFiles((dir, name) -> name.toLowerCase().endsWith(".txt"));

java file filter java-6

Is there a specific reason you want to use FileNameExtensionFilter? I know this works.. 

private File[] getNewTextFiles() {    return dir.listFiles(new FilenameFilter() {        @Override        public boolean accept(File dir, String name) {            return name.toLowerCase().endsWith(".txt");        }    });}
