Class 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]);
     }
