An anonymous inner class is an inner class without a name. To my knowlege they are usually used as event handlers. If you only need a certain event handler in one place, why bother creating it as a separate class when you can just give all the relevant information right where the object is used?

doThisButton.addActionListener(
    // anonymous inner class
    new ActionListener()
    {
        public void actionPerformed( ActionEvent ae)
        {
            // code that accomplishes whatever the doThis button
            // should make happen
        }
    } // anonymous inner class ends
);  // call to addActionListener ends
