Converts an array of {@code Long}s to an array of {@code long}s.
Returns {@code null} if the given array is {@code null}. Does not
modify the input array.

@param a the {@code Long} array to convert.

@return the corresponding {@code long} array.

@throws NullPointerException if {@code a} contains a {@code null} value.
Converts an array of { @code Long } s to an array of { @code long } s . Returns { @code null } if the given array is { @code null } . Does not modify the input array .
