Modern Java noteThis archive has been refreshed for Java 25 LTS. Core language concepts remain useful, while outdated setup instructions and browser-era Java are labeled or replaced. Java 26 is the current feature release; Java 25 is used here as the stable teaching baseline.

      y    = rand.nextInt( height );
      size = rand.nextInt( 20 );

QUESTION 16:
