//使用Stream of 创建流

        Stream.of(1).forEach(x-> System.out.println(x));

        //使用Arrays.stream

        int num[] = {1,2,3,4,5,65,76};         Arrays.stream(num).forEach(x-> System.out.println(x));

        //使用Stream.iterate

        Stream.iterate(1,x->x+1).limit(10).forEach(x-> System.out.println(x));

        //使用Stream.generate

        Stream.generate(Math::random).limit(10).forEach(x-> System.out.println(x));

        //从集合创建

        List<String> list = Arrays.asList("12","er","rt","22");         list.stream().forEach(x-> System.out.println(x));                  //使用IntStream等的 range和rangeClose         IntStream.range(5,10).forEach(x-> System.out.println(x));         IntStream.rangeClosed(5,10).forEach(x-> System.out.println(x));
