How to return multiple objects from a Java method?

Question

I want to return two objects from a Java method and was wondering what could be a good way of doing so?

The possible ways I can think of are: return a HashMap<

Answer 1

I almost always end up defining n-Tuple classes when I code in Java. For instance:

public class Tuple2 {
  private T1 f1;
  private T2 f2;
  public Tuple2(T1 f1, T2 f2) {
    this.f1 = f1; this.f2 = f2;
  }
  public T1 getF1() {return f1;}
  public T2 getF2() {return f2;}
}

I know it's a bit ugly, but it works, and you just have to define your tuple types once. Tuples are something Java really lacks.

EDIT: David Hanak's example is more elegant, as it avoids defining getters and still keeps the object immutable.
