Replace for loop with java 8 foreach for updating values

Question

I\'m looking to replace the following for loop with an elegant java 8 stream or lambda solution. Is there anything concise and efficient?

    public static v         


        

Answer 1

There is no way to access previous element in the java stream. You might use IntStream#range but it doesn't look elegant:

IntStream.range(1, myList.size())
        .forEachOrdered(i -> myList.set(i, myList.get(i) + myList.get(i - 1) / 2));
