Consider the following code sample:

import java.util.Arrays;
import java.util.stream.LongStream;
import java.util.stream.StreamSupport;

public class StreamFromSpliterator {
    public static void main(String[] args) {

        getLongStream().noneMatch(e -> {
            System.err.println(e);
            return false;
        });
        System.err.println("---");
        getLongStream().allMatch(e -> {
            System.err.println(e);
            return true;
        });
        System.err.println("---");
        getLongStream().anyMatch(e -> {
            System.err.println(e);
            return false;
        });
    }

    private static LongStream getLongStream() {
        return StreamSupport.longStream(Arrays.spliterator(new long[]{1, 2, 3, 4}), true);
    }
}
---------------------------------

The order of the consumed elements doesn't correspond the original.
The output will be like:


3
2
1
4
---
3
2
4
1
---
3
4
2
1
