Storing and managing huge arrays

[trust]

My current aim is to store huge arrays of
seven different types. I don't not know which type exactly do I need,
it depends of file type that i'm going to read.
My idea is to write a class that has seven array. Six of
them are allways null and one stores my data. But this decision looks
quite gracelessly...

So my questions are:

1. Is there any more elegant way to store my data?

2. Is arrays sizable for this kind of job? (Storing huge(1
000 000 elements) arrays)

1. Use a 2D array and have the 'x' be the array number and the 'y' be the value you would have used for a 1D array.

2. Yes.

This is quite an old thread. But I just feel to add something more.

Actually I don't think it's a good idea to keep that much of data in arrays. Because all those are allocated in your memory. Just think what happen if you have millions of such array elements, because of your single array, since all the others are always null. And also I wonder what's the point just define six more arrays if you are not going to use them.

In such cases most suitable things is deal with the databases. Indexing, paging and lots of other technologies are available to handle huge databases.
