Is this a variation of an anonymous inner class?

Here is an example

JPanel panel = new JPanel(){
    @Override
    protected void paintComponent(Graphics g){
        // do stuff
    }

    @Override
    public Dimension getPreferredSize(){
        // do stuff
    }
};

Would this just be a variation of an anonymous inner class, or is it something else entirely?

You may be confused about the anonymity of the class because at first blush it looks like you're defining panel to be an instance of JPanel. However, that's not what you are doing. Instead you are defining a sub-class of JPanel, which is a new class and creating panel to be an instance of this new sub-class. What is the name of this new class? Well, it doesn't have one and hence that's what makes it anonymous!
