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]);
}
