java中Random的使用

        /**
         * 随机点名器
         */
        Random random = new Random();
        String[] names = {"刘备","曹操","关羽","张飞","赵云","孙权"};
        int index = random.nextInt(names.length);
        System.out.println("随机抽取到的名字为：" + names[index]);

        random.ints(0,100).limit(10).sorted().forEach(System.out::println);
