/**
 * Accepts a selection if it is acceptable to both of two {@link FilenameFilter}s.
 * This takes two {@link FilenameFilter}s as input.
 *
 * <p>Eg., to print all files beginning with <code>A</code> and ending with <code>.java</code>:</p>
 *
 * <pre>
 * File dir = new File(".");
 * String[] files = dir.list( new AndFileFilter(
 *         new PrefixFileFilter("A"),
 *         new ExtensionFileFilter(".java")
 *         )
 *     );
 * for ( int i=0; i&lt;files.length; i++ )
 * {
 *     System.out.println(files[i]);
 * }
 * </pre>
