public class FilePrefixFilter

extends java.lang.Object

implements java.io.FilenameFilter

FilePrefixFilter can be used by java.io.File and java.awt.FileDialog to select files with a given file prefix. A file prefix is the text before a "." in the file name. So foo.bar.txt has the prefix foo, and foo.bar. Given either prefix the filter will accept the file foo.bar.txt. That is when The comparison of the file extension is not case sensitive. So lost is considered the same as LOST A sample use:

		File currentDirectory = new File( "." );
		String[] listing = currentDirectory.list( new FilePrefixFilter("lost"));
 

gives all the file starting with "lost" in the current directory.
