Question

I’m doing a project in Java in which I’m looking at the frequency characters occur after each other character in a text. When I’m collecting my results, I’m storing them in a 2d array of ints. However, in the same results table, I want to store some results about the whole thing.

Is it possible to have an array where some of the elements are arrays, and others are primitives?

Answer 1

Yes, you can have Object[] and store a mix a types, although it would have to be the wrapper Integer (not the primitive int). (Note: you could “cheat” and save each int as a single-element array int[], thus making it an Object, but “don’t try this at home”)

But even if you could, an array isn’t the right approach. Instead, create a class for this.

Try something like this:

public class FrequencyAnalysis {
    private int[] frequencies;
    private String info;
    private Date lastRun;
    // etc
}
