public class WildcardFileFilter extends AbstractFileFilter implements Serializable
This filter selects files and directories based on one or more wildcards. Testing is case-sensitive by default, but this can be configured.
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 check is case-sensitive by default.
See FilenameUtils.wildcardMatchOnSystem(java.lang.String, java.lang.String) for more information.
For example:
File dir = new File(".");
FileFilter fileFilter = new WildcardFileFilter("*test*.java~*~");
File[] files = dir.listFiles(fileFilter);
for (int i = 0; i < files.length; i++) {
System.out.println(files[i]);
}
