rem(double k)
Note that this method should be called
remove() , but the clash
with the similarly named index-based method in the List interface
forces us to use a distinguished name. |

toArray(double[] a)
Returns a primitive type array containing the items of this collection.
|

strengthened in the corresponding type-specific class,
but was weakened by the fact that this interface extends Collection
.
