Operations on Arrays with Stream

int[] a = {2,5,4,6,9,7,4,5,8,7,4,5,6,3};
        int[] b = {6,9,8,7,4,2,3,6,5,2,1,4,7,8,5,6,3,6};

        //combine arrays
        IntStream combined = Stream.of(a,b).flatMapToInt(IntStream::of);

        //remove duplicates
        IntStream distinct = combined.distinct();

        //sort
        IntStream sorted = distinct.sorted();

        //filter some value
        IntStream lessThenFive = sorted.filter(n -> n<=5);

        //print array
        lessThenFive.forEach(System.out::println);


        //sum of all
//        int sum = sorted.sum();

        /*
        Note: sum and forEach are termianl methods so the stream will be close
        */
