13 mar 2024 · We can find the Pair class in the javafx.util package. The constructor of this class takes two arguments, a key and its corresponding value: Integer key = pair.getKey(); String value = pair.getValue(); This example illustrates a simple Integer to String mapping using the Pair concept.
18 maj 2011 · For example: public class Pair<T,U> { public final T first; public final U second; public static <T,U> Pair<T,U> of(T first, U second); } So that the end-user can write: return Pair.of (a, b); and. Pair<A,B> p = someThing (); doSomething (p.first); doSomethingElse (p.second);
