/**
 * This filter accepts {@code File}s that can be read.

 * <h2>Using Classic IO</h2>
 * <pre>
 * File dir = new File(".");
 * String[] files = dir.list(CanReadFileFilter.CAN_READ);
 * for (String file : files) {
 *     System.out.println(file);
 * }
 * </pre>

 * Example, showing how to print out a list of the current directory's <i>un-readable</i> files:
 *
 * <pre>
 * File dir = new File(".");
 * String[] files = dir.list(CanReadFileFilter.CANNOT_READ);
 * for (String file : files) {
 *     System.out.println(file);

 * for (String file : files) {
