public class PrefixFileFilter extends AbstractFileFilter implements java.io.Serializable
For example, to print all files and directories in the
current directory whose name starts with Test:
File dir = new File(".");
String[] files = dir.list( new PrefixFileFilter("Test") );
for ( int i = 0; i < files.length; i++ ) {
System.out.println(files[i]);
}
