Index of elements supported with foreach

jOOQ / jOOL

jOOλ - The Missing Parts in Java 8 jOOλ improves the JDK libraries in areas where the Expert Group's focus was elsewhere. It adds tuple support, function support, and a lot of additional functionality around sequential Streams. The JDK 8's main efforts (default methods, lambdas, and the Stream API) were focused around maintaining backwards compatibility and implementing a functional API for parallelism.

See a code segment below java

Versions:

jOOλ:

Java:

public static <E> void forEach(Iterable<? extends E> elements, BiConsumer<Integer, ? super E> action) {
    Objects.requireNonNull(elements);
    Objects.requireNonNull(action);

    int index = 0;
    for (E element : elements) {
        action.accept(index++, element);
    }
}

jOOλ has this functionality that does exactly the same thing, in a different way:

Seq.zipWithIndex(elements)
   .forEach(...)
