Two-dimensional array of different types

data-structures, java

Solution

Arrays can only contain one type. If that type happens to be `Object` then it can store `Object` and any of its sub-types, but that doesn't really sound like what you're trying to accomplish here.

It sounds like what you're describing is a 2D array to store database information, with each element in the array being a column in one of the rows. This isn't an array of records, it's an array of column data.

Instead, just store a one-dimensional array of records, where each element of the array is a reference to the entire DB row.

Problem

I want to create a two-dimensional array in which I want to store records from the database. So lets say that the first is of type `int` and the second of type `String` (here I am describing just one record so basically types of db columns). How can I do it? Is an array the right data structure for that?
