Java stream order of processing

Question

I have the following:

LinkedList ints = new LinkedList();
//fill it with some ints
Stream stream = ints.stream();
//process the         


        

Answer 1

Depends on the processing you are applying to the stream... especially using parallel()

import java.util.LinkedList;
import java.util.function.Consumer;
import java.util.stream.Stream;

public class Streaming {

    public static void main(String[] args) {
        LinkedList ints = new LinkedList();
        for(int i = 0 ; i < 100; i++) {
            ints.add(i);
        }
        Stream stream = ints.stream();
        // will not be ordered
        stream.parallel().forEach(new Consumer() {

            @Override
            public void accept(Integer t) {
                System.out.println(t);
            }

        });

        stream = ints.stream();
        // will be ordered
        stream.parallel().forEachOrdered(new Consumer() {

            @Override
            public void accept(Integer t) {
                System.out.println(t);
            }

        });
    }
}
