In the previous lesson, Timer and SwingWorker in Java Swing, we learned to use Timer and SwingWorker. Today, we're going to create an application displaying an analog and digital clock, the user will be able to choose which one to display. We'll learn a lot of new things about rendering and try the JRadioButton, JButtonGroup, JPanel, and JCheckBox components.

Our app will look as follows:
