This filter accepts Files that can be executed.

Example, showing how to print out a list of the current directory's executable files:

 }

Example, showing how to print out a list of the current directory's un-executable files: 

 File dir = new File(".");
 String[] files = dir.list( CanExecuteFileFilter.CANNOT_EXECUTE );
 for ( int i = 0; i < files.length; i++ ) {
     System.out.println(files[i]);
