java.lang.Object
org.apache.commons.io.filefilter.AbstractFileFilter
org.apache.commons.io.filefilter.SuffixFileFilter
All Implemented Interfaces:
FileFilter, FilenameFilter, Serializable, IOFileFilter

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:

 File dir = new File(".");
 String[] files = dir.list( new SuffixFileFilter(".java") );
 for (int i = 0; i < files.length; i++) {
     System.out.println(files[i]);
 }
