WildcardFilter
public class WildcardFilter extends AbstractFileFilter (Code)
Filters files using the supplied wildcards.

This filter selects files, but not directories, based on one or more wildcards and using case-sensitive comparison.

The wildcard matcher uses the characters '?' and '*' to represent a single or multiple wildcard characters. This is the same as often found on Dos/Unix command lines. The extension check is case-sensitive. See FilenameUtils.wildcardMatch for more information.

For example:

 File dir = new File(".");
 FileFilter fileFilter = new WildcardFilter("*test*.java~*~");
 File[] files = dir.listFiles(fileFilter);
 for (int i = 0; i < files.length; i++) {
 System.out.println(files[i]);
 }
