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>, PathFilter, PathVisitor, IOFileFilter

public class CanExecuteFileFilter
extends AbstractFileFilter
implements Serializable

This filter accepts Files that can be executed.

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

Using Classic IO

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