As you can see in the title, I get an error when I try to read a JSON file which is available at the Riot-Games API. I try to return the current tier and rank of a user using its summonerID. I don't get this error when I try to obtain the summonerID.
I guess the problem is that the JSON file starts and ends with "**[**" and "**]**". Therefore I'm searching a solution on how to extract some parts of it (e.g.: tier, rank and leaguePoints).

**This is how I recieve the summonerID:** 

```
public static String getSummonerID(String summoner) throws IOException, JSONException {
    JSONObject json = readJsonFromUrl("https://euw1.api.riotgames.com/lol/summoner/v3/summoners/by-name/" + summoner +"?api_key="+ api_key);
    return json.get("id").toString();
}

```

**This is how I try to recieve the informations about the current tier:**

```
public static String getSummonerTierSoloQ(String summoner) throws IOException, JSONException {
    JSONObject json = readJsonFromUrl("https://euw1.api.riotgames.com/lol/league/v3/positions/by-summoner/" + getSummonerID(summoner) +"?api_key="+ api_key);
    return json.toString();
}

```

**The JSON file to obtain looks like this:**

```
[
    {
        "leagueId": "",
        "leagueName": "Soraka's Mercenaries",
        "tier": "SILVER",
        "queueType": "RANKED_SOLO_5x5",
        "rank": "III",
        "playerOrTeamId": "",
        "playerOrTeamName": "JieBäf",
        "leaguePoints": 58,
        "wins": 142,
        "losses": 134,
        "veteran": true,
        "inactive": false,
        "freshBlood": false,
        "hotStreak": false
    },
    {
        "leagueId": "",
        "leagueName": "Sion's Marksmen",
        "tier": "SILVER",
        "queueType": "RANKED_FLEX_SR",
        "rank": "IV",
        "playerOrTeamId": "",
        "playerOrTeamName": "JieBäf",
        "leaguePoints": 23,
        "wins": 96,
        "losses": 98,
        "veteran": true,
        "inactive": false,
        "freshBlood": false,
        "hotStreak": false
    }
]

```

**And the exact error code is:**

```
org.json.JSONException: A JSONObject text must begin with '{' at 1 [character 2 line 1]
        at org.json.JSONTokener.syntaxError(JSONTokener.java:433)
        at org.json.JSONObject.<init>(JSONObject.java:183)

        at dev.reader.JsonReader.output(JsonReader.java:45)
        at dev.main.Load.main(Load.java:15)

```

**Almost forgot about the methods readJsonFromURL and readAll:**

```
public static JSONObject readJsonFromUrl(String url) throws IOException, JSONException {
    InputStream is = new URL(url).openStream();
    try {
      BufferedReader rd = new BufferedReader(new InputStreamReader(is, Charset.forName("UTF-8")));
      String jsonText = readAll(rd);
      JSONObject json = new JSONObject(jsonText);
      return json;
    } finally {
      is.close();
    }
}

private static String readAll(Reader rd) throws IOException {
    StringBuilder sb = new StringBuilder();
    int cp;
    while ((cp = rd.read()) != -1) {
        sb.append((char) cp);
    }
    return sb.toString();
}

```

Thanks for all your assistance :D
