Android programmers could use BasicNameValuePair

Update:

BasicNameValuePair is now deprecated (API 22). Use Pair instead.

Example usage:

Pair<Integer, String> simplePair = new Pair<>(42, "Second");
Integer first = simplePair.first; // 42
String second = simplePair.second; // "Second"

Try Generics and create your own class if you don't like java collections:

public class Pair<K, V> {

    private K key;

    private V value;

    public Pair(K key, V value) {
        this.key = key;
        this.value = value;
    }

    public K getKey() {
        return key;
    }

    public void setKey(K key) {
        this.key = key;
    }

    public V getValue() {
        return value;
    }

    public void setValue(V value) {
        this.value = value;
    }

    public static void main(String[] args) {
        Pair<String, String> pair = new Pair<String, String>("key", "value");
        System.out.println(pair.getKey());
        System.out.println(pair.getValue());
    }

}
