// Example 10-9: Using all the objects in one sketch

Catcher catcher;    // One catcher object
Timer timer;        // One timer object
Drop[] drops;       // An array of drop objects
int totalDrops = 0; // totalDrops

  timer.start();             // Starting the timer
}

  // From Part 1. The Catcher!

  // From Part 3. The Timer!
  // Check the timer

  // Move and display all drops
