public class SuffixFileFilter extends AbstractFileFilter implements Serializable
Filters files based on the suffix (what the file name ends with). This is used in retrieving all the files of a particular type.

For example, to retrieve and print all *.java files in the current directory:

Using Classic IO

 File dir = new File(".");
 String[] files = dir.list(new SuffixFileFilter(".java"));
 for (String file : files) {
     System.out.println(file);
 }
 

Using NIO

 final Path dir = Paths.get("");
 final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(new SuffixFileFilter(".java"));
 //
 // Walk one dir
 Files.walkFileTree(dir, Collections.emptySet(), 1, visitor);
 System.out.println(visitor.getPathCounters());
 System.out.println(visitor.getFileList());
 //
 visitor.getPathCounters().reset();
 //
 // Walk dir tree
 Files.walkFileTree(dir, visitor);
 System.out.println(visitor.getPathCounters());
 System.out.println(visitor.getDirList());
 System.out.println(visitor.getFileList());

      public SuffixFileFilter(String... suffixes)
      Constructs a new Suffix file filter for an array of suffixes.

      The array is not cloned, so could be changed after constructing the instance. This would be inadvisable however.
