java流的建立

        //使用Stream of 建立流
        Stream.of(1,2,3,43,5,65).forEach(x-> System.out.println(x));

        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));

        //從集合建立
        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));
