What is the equivalent of the C++ Pair in Java?

Question

Is there a good reason why there is no Pair in Java? What would be the equivalent of this C++ construct? I would rather avoid reimplementing my own.<

Answer 1

public class Pair {

    private final K element0;
    private final V element1;

    public static  Pair createPair(K key, V value) {
        return new Pair(key, value);
    }

    public Pair(K element0, V element1) {
        this.element0 = element0;
        this.element1 = element1;
    }

    public K getElement0() {
        return element0;
    }

    public V getElement1() {
        return element1;
    }

}

usage :

Pair pair = Pair.createPair(1, "test");
pair.getElement0();
pair.getElement1();

Immutable, only a pair !
