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\",          


        

Answer 1

Just for completeness here's the solution involving my StreamEx library:

String[] names = {"Sam","Pamela", "Dave", "Pascal", "Erik"};
EntryStream.of(names)
    .filterKeyValue((idx, str) -> str.length() <= idx+1)
    .values().toList();

Here we create an EntryStream which extends Stream> and adds some specific operations like filterKeyValue or values. Also toList() shortcut is used.
