Description

You are designing a remote for controlling devices in your home. Currently, you have a single device you want to control: color-changing light panels. You are planning on adding more devices in the future.

There are currently three commands you want to send to the panels:

• on,
• change brightness to 10 (dim), and
• change color to blue.

Leverage the Command pattern to design a RemoteControl class that controls devices. Configure the remote to control your color-changing light panels. The remote should be able to undo the three most recent commands issued.

Criteria

1. Recall or research what the heck the Command Pattern is.
2. Add a main method to your RemoteControl class demonstrating
   1. the construction of a remote,
   2. execution of the three color-changing light panel commands (on, change brightness to 10 (dim), and change color to blue),
   3. undoing the three most recent commands issued.
