Which SWT class or interface ensures that CBox recreates its color at a set interval?

  1. Timer

  2. Runnable

  3. ScheduledExecutorService

  4. Display.timerExec

The correct answer is: Runnable

The class or interface that ensures that CBox recreates its color at a set interval is Runnable. This is because Runnable contains the necessary functionality to execute code repeatedly at a set interval. Options A, C, and D are incorrect because Timer, ScheduledExecutorService, and Display.timerExec do not have the same functionality as Runnable and are not specifically designed for this task.
