Is there a concise way to iterate over a stream with indices in Java 8?

Question

Is there a concise way to iterate over a stream whilst having access to the index in the stream?

String[] names = {\"Sam\",\"Pamela\", \"Dave\", \"Pascal\",

With https://github.com/poetix/protonpack u can do that zip:

String[] names = {"Sam","Pamela", "Dave", "Pascal", "Erik"};

List nameList;
Stream indices = IntStream.range(0, names.length).boxed(); 

nameList = StreamUtils.zip(indices, stream(names),SimpleEntry::new)
        .filter(e -> e.getValue().length() <= e.getKey()).map(Entry::getValue).collect(toList());                   

System.out.println(nameList);
