Java: How to write a `zip` function? What should be the return type?

Question

What should be the return type of a zip function? (zip as in most other languages, e.g. read here)

I thought about some Pair-type but that

Answer 1

Here is a start.

public class Pair
{
    private T1 first;
    private T2 second;

    public Pair(T1 first, T2 second)
    {
        this.first = first;
        this.second = second;
    }

    public T1 getFirst()
    {
        return first;
    }

    public T2 getSecond()
    {
        return second;
    }
}
