java.lang.Object
- org.apache.commons.io.filefilter.AbstractFileFilter
- - org.apache.commons.io.filefilter.EmptyFileFilter

All Implemented Interfaces:

java.io.FileFilter, java.io.FilenameFilter, java.io.Serializable, IOFileFilter
```
public class EmptyFileFilter
extends AbstractFileFilter
implements java.io.Serializable
```
This filter accepts files or directories that are empty.
If the File is a directory it checks that it contains no files.
Example, showing how to print out a list of the current directory's empty files/directories:
```
 File dir = new File(".");
 String[] files = dir.list( EmptyFileFilter.EMPTY );
 for ( int i = 0; i < files.length; i++ ) {
     System.out.println(files[i]);
 }
 
```
Example, showing how to print out a list of the current directory's non-empty files/directories:
```
 File dir = new File(".");
 String[] files = dir.list( EmptyFileFilter.NOT_EMPTY );
 for ( int i = 0; i < files.length; i++ ) {
     System.out.println(files[i]);
 }
 
```
