Package org.apache.commons.io.filefilter

# Class CanExecuteFileFilter

java.lang.Object
org.apache.commons.io.filefilter.AbstractFileFilter
org.apache.commons.io.filefilter.CanExecuteFileFilter

All Implemented Interfaces:
  `FileFilter`, `FilenameFilter`, `Serializable`, `FileVisitor<Path>`, `PathMatcher`, `PathFilter`, `PathVisitor`, `IOFileFilter`

public class CanExecuteFileFilter extends AbstractFileFilter implements Serializable
This filter accepts `File`s that can be executed.

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

## Using Classic IO

     File dir = FileUtils.current();
     String[] files = dir.list(CanExecuteFileFilter.CAN_EXECUTE);
     for (String file : files) {
         System.out.println(file);
     }

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

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