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

you don't need a map necessarily
that is the closest lambda to the LINQ example:

int[] idx = new int[] { 0 };
Stream.of( names ).filter( name -> name.length() <= idx[0]++ ).collect( Collectors.toList() );
