How to get data from nested json array android

i am trying to get data of nested json array without success so far. maybe someone have an idea or direction how to do it right. my code is Challenge class

public class ChallengeModel {

private String ChallengeID;
private String ChallengeDate;
private String ChallengeName;
private String ChallengeIcon;
private String BetID;
private ChallengeItem challengeItem[];

public String getChallengeID() { return ChallengeID; }
public void setChallengeID(String challengeID) {
    ChallengeID = challengeID;
}
public String getChallengeDate() {
    return ChallengeDate;
}
public void setChallengeDate(String challengeDate) {
    ChallengeDate = challengeDate;
}
public String getChallengeName() {
    return ChallengeName;
}
public void setChallengeName(String challengeName) {
    ChallengeName = challengeName;
}
public String getChallengeIcon() {
    return ChallengeIcon;
}
public void setChallengeIcon(String challengeIcon) {
    ChallengeIcon = challengeIcon;
}
public String getBetID() {
    return BetID;
}
public void setBetID(String betID) {
    BetID = betID;
}
public ChallengeItem[] getChallengeItem() {
    return challengeItem;
}
public void setChallengeItem(ChallengeItem[] challengeItem) { 
this.challengeItem = challengeItem; }}

In the above class there is an Array of nested class

public class ChallengeItem {

private String ChallengeItemID;
private String ChallengeID;
private String MatchID;
private String TeamAName;
private String TeamBName;
private String TeamAScore;
private String TeamBScore;
private String MatchDate;
private String MatchTime;
private String Venue;
private String VenuCity;
private String TeamAValue;
private String TeamBValue;

public String getChallengeItemID() {
    return ChallengeItemID;
}

public void setChallengeItemID(String challengeItemID) {
    ChallengeItemID = challengeItemID;
}

public String getChallengeID() {
    return ChallengeID;
}

public void setChallengeID(String challengeID) {
    ChallengeID = challengeID;
}

public String getMatchID() {
    return MatchID;
}

public void setMatchID(String matchID) {
    MatchID = matchID;
}

public String getTeamAName() {
    return TeamAName;
}

public void setTeamAName(String teamAName) {
    TeamAName = teamAName;
}

public String getTeamBName() {
    return TeamBName;
}

public void setTeamBName(String teamBName) {
    TeamBName = teamBName;
}

public String getTeamAScore() {
    return TeamAScore;
}

public void setTeamAScore(String teamAScore) {
    TeamAScore = teamAScore;
}

public String getTeamBScore() {
    return TeamBScore;
}

public void setTeamBScore(String teamBScore) {
    TeamBScore = teamBScore;
}

public String getMatchDate() {
    return MatchDate;
}

public void setMatchDate(String matchDate) {
    MatchDate = matchDate;
}

public String getMatchTime() {
    return MatchTime;
}

public void setMatchTime(String matchTime) {
    MatchTime = matchTime;
}

public String getVenue() {
    return Venue;
}

public void setVenue(String venue) {
    Venue = venue;
}

public String getVenuCity() {
    return VenuCity;
}

public void setVenuCity(String venuCity) {
    VenuCity = venuCity;
}

public String getTeamAValue() {
    return TeamAValue;
}

public void setTeamAValue(String teamAValue) {
    TeamAValue = teamAValue;
}

public String getTeamBValue() {
    return TeamBValue;
}

public void setTeamBValue(String teamBValue) {
    TeamBValue = teamBValue;
}

public String getDrawValue() {
    return DrawValue;
}

public void setDrawValue(String drawValue) {
    DrawValue = drawValue;
}

private String DrawValue;
}

My question is, how do i get the data from json to the nested array (The first array is working great)

public class ChallengeJsonConvert {

public static List<ChallengeModel> challengesRequest(String content){
    try {

        JSONArray challengesArray = new JSONArray(content);

        List<ChallengeModel> challengeModelList = new ArrayList<>();

        for(int i = 0; i < challengesArray.length(); i++){

            JSONObject obj = challengesArray.getJSONObject(i);
            ChallengeModel challenge = new ChallengeModel();
            challenge.setBetID(obj.getString("BetID"));
            challenge.setChallengeDate(obj.getString("ChallengeDate"));
            challenge.setChallengeIcon(obj.getString("ChallengeIcon"));
            challenge.setChallengeID(obj.getString("ChallengeID"));
            challenge.setChallengeName(obj.getString("ChallengeName"));
            challengeModelList.add(challenge);

        }
        return challengeModelList;
    } catch (JSONException e) {
        e.printStackTrace();
        return null;
    }
}
}

This is the results from the server

Use list made changes in your class copy and generate getter setter

ChallengeModel 

public class ChallengeModel {
    private String ChallengeID;
    private String ChallengeDate;
    private String ChallengeName;
    private String ChallengeIcon;
    private String BetID;
    private List<ChallengeItem> challengeItem;
    //TODO
    //Generate Getter and setter
}

ChallengeItem 

public class ChallengeItem {
    private String ChallengeItemID;
    private String ChallengeID;
    private String MatchID;
    private String TeamAName;
    private String TeamBName;
    private String TeamAScore;
    private String TeamBScore;
    private String MatchDate;
    private String MatchTime;
    private String Venue;
    private String VenuCity;
    private String TeamAValue;
    private String TeamBValue;
    //TODO
    //Generate Getter and setter
}

ChallengeJsonConvert

public class ChallengeJsonConvert {
    public static List<ChallengeModel> challengesRequest(String content) {
        try {
            JSONArray challengesArray = new JSONArray(content);
            List<ChallengeModel> challengeModelList = new ArrayList<>();
            for (int i = 0; i < challengesArray.length(); i++) {
                JSONObject obj = challengesArray.getJSONObject(i);
                ChallengeModel challenge = new ChallengeModel();
                challenge.setBetID(obj.getString("BetID"));
                challenge.setChallengeDate(obj.getString("ChallengeDate"));
                challenge.setChallengeIcon(obj.getString("ChallengeIcon"));
                challenge.setChallengeID(obj.getString("ChallengeID"));
                challenge.setChallengeName(obj.getString("ChallengeName"));
                JSONArray challengeItemArray = obj.getJSONArray("challengeItem");
                for (int j = 0; j < challengeItemArray.length(); j++) {

                    JSONObject challengeObject = challengeItemArray.getJSONObject(j);
                    ChallengeItem challengeItem = new ChallengeItem();
                    challengeItem.setChallengeItemID(challengeObject.getString("CallengeItemID"));
                    //TODO 
                    //Get other object and set into challengeItem 
                    challenge.getChallengeItem().add(challengeItem);
                }

                challengeModelList.add(challenge);
            }
            return challengeModelList;
        } catch (JSONException e) {
            e.printStackTrace();
            return null;
        }
    }
}
