getExtension

public String getExtension(File f)
Return the extension portion of the file's name .

See Also:
getExtension(java.io.File), FileFilter.accept(java.io.File)

addExtension

public void addExtension(String extension)
Adds a filetype "dot" extension to filter against. For example: the following code will create a filter that filters out all files except those that end in ".jpg" and ".tif": ExampleFileFilter filter = new ExampleFileFilter(); filter.addExtension("jpg"); filter.addExtension("tif"); Note that the "." before the extension is not needed and will be ignored.


getDescription
