常用API之List

public static void main(String[] args) {
        Jedis jedis = new Jedis("127.0.0.1",6379);
        jedis.auth("12345");
        jedis.flushDB();

        System.out.println("==================添加一个List==================");
        System.out.println(jedis.lpush("collections","ArrayList","Vector","Stack","HashMap","WeakHashMap","LinkedHashMap"));
        System.out.println(jedis.lpush("collections","HashSet"));
        System.out.println(jedis.lpush("collections","TreeSet"));
        System.out.println(jedis.lpush("collections","TreeMap"));
        System.out.println("collections的内容:"+jedis.lrange("collections",0,-1));
        System.out.println("collections区间0-3的元素:"+jedis.lrange("collections",0,3));

        System.out.println("=============================================");
        //删除列表指定的值,第二个参数为删除的个数(有重复时),后add进去的值先被删,类似于出栈
        System.out.println("删除指定元素个数:"+jedis.lrem("collections",2,"HashMap"));
        System.out.println("collections的内容:"+jedis.lrange("collections",0,-1));
        System.out.println("删除下表0-3区间之外的元素:"+jedis.ltrim("collections",0,3));
        System.out.println("collections的内容:"+jedis.lrange("collections",0,-1));
        System.out.println("collections列表出栈(左端):"+jedis.lpop("collections"));
        System.out.println("collections的内容:"+jedis.lrange("collections",0,-1));
        System.out.println("collections添加元素,从列表右端,与lpush相对应:"+jedis.rpush("collections","EnumMap"));
        System.out.println("collections的内容:"+jedis.lrange("collections",0,-1));
        System.out.println("collections列表出栈(右端):"+jedis.rpop("collections"));

        System.out.println("=============================================");
        System.out.println("collections长度:"+jedis.llen("collections"));
        System.out.println("获取collections下标为2的元素:"+jedis.lindex("collections",2));
        System.out.println("=============================================");
        System.out.println(jedis.lpush("sortedList","2","3","5","0","9","1"));
        System.out.println("sortedList排序前:"+jedis.lrange("sortedList",0,-1));
        System.out.println(jedis.sort("sortedList"));
        System.out.println("sortedList排序后:"+jedis.lrange("sortedList",0,-1));

    }
