The equivalent in Java would be something like

// Prior definitions

interface RespondToHandler
{
    public void doFormatting(FormatThingummy format);
}

void respondTo(RespondToHandler)
{
    // ...
}

// Equivalent of your quoted code

respondTo(new RespondToHandler(){
    public void doFormatting(FormatThingummy format)
    {
        format.html();
        format.xml();
    }
});
