Answer 1

No. Java methods can only return one result (void, a primitive, or an object), and creating a struct-type class like this is exactly how you do it.

As a note, it is frequently possible to make classes like your ReturningValues immutable like this:

public class ReturningValues {
    public final String value;
    public final int index;

    public ReturningValues(String value, int index) {
        this.value = value;
        this.index = index;
    }
}

This has the advantage that a ReturningValues can be passed around, such as between threads, with no concerns about accidentally getting things out of sync.
