## Example: A Color Mixer

- How do you know if there is a slider?
  - Buy a book that illustrates all Swing components
  - Run sample application included in the JDK that shows off all Swing components
  - Look at the names of all of the classes that start with J
    - `JSlider` seems like a good candidate
- Next, ask a few questions:
  - How do I construct a `JSlider`?
  - How can I get notified when the user has moved it?
  - How can I tell to which value the user has set it?
- After mastering sliders, you can find out how to set tick marks, etc.
