  final PVector[] vecs = {
    new PVector(), 
    new PVector(10, 20), 
    new PVector(TAU, EPSILON, sqrt(3)) };
  
  // display initialized values of each PVector element in the array:
  printArray(vecs);
  println();
  
  // display 2nd element (index 1):
  println(vecs[1]);
  
  // reassign a new PVector object to index 1 thus discarding the old:
  vecs[1] = PVector.random3D(this);
  println(vecs[1], ENTER);
  
  // access & set new values for the PVector instance in index 0 w/o reassignment:
  vecs[0].set(Float.NaN, MAX_FLOAT, DEG_TO_RAD);
  println(vecs[0], ENTER);
  
  // display current values after all those changes:
  printArray(vecs);
  exit();
