## 24.23 java.io.FilenameFilter (JDK 1.0)

###

This interface defines the `accept()` method that must be implemented by any object that filters filenames (i.e., selects a subset of filenames from a list of filenames). There are no standard `FilenameFilter` classes implemented by Java, but objects that implement this interface are used by the `java.awt.FileDialog` object, and by the `File.list()` method. A typical `FilenameFilter` object might check that the specified `File` represents a file (not a directory), is readable (and possibly writable as well), and that its name ends with some desired extension.

    public abstract interface FilenameFilter {
        // Public Instance Methods
                public abstract boolean accept(File dir, String name);
    }

### Passed To:

File.list(), FileDialog.setFilenameFilter(), FileDialogPeer.setFilenameFilter()

### Returned By:

FileDialog.getFilenameFilter()
