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 = 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]); }
