In the preceding example, we called the bounce() method inside the move() method. Alternatively, you could choose to invoke it from draw():

void draw() {

...

b1.move();

b1.bounce();

b1.display();

...

} // draw()

You will notice that object-oriented design and development allows for incremental enhancements and, at the same time, keeps your programs well organized. Also, at each step, there are many decisions that need to be made: What attributes to add? How and when to initialize them? How are object instances customized? What behaviors are needed? How they are invoked? As you make these decisions you will be confronted with choices in the implementation. It is always possible to achieve the same behavior in a sketch out of many possible implementation choices. Which choices you make should be based on keeping a clean design, ensuring future extendibility, and providing as many opportunities for parameterization as might be sensible.
