    So I'm attempting to use a snippet by - alotoffluffy, Its a Ge price grabber, But everytime I try to call

    log("Item price: " + PriceFetcher.getPricedItem(861).getOverallAverage());

    It returns nothing... Here's the snippet below

    import com.google.gson.Gson;
    import com.google.gson.JsonObject;
    import com.google.gson.JsonParser;
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.net.URL;
    public class PriceFetcher {
        private static final long HALF_HOUR = 1800000;
        private static final String url = "https://rsbuddy.com/exchange/summary.json";
        private static long cacheTime;
        private static String cache = null;
        public static PricedItem getPricedItem(int id){
            if (shouldUpdate())
            JsonObject query = new JsonParser().parse(cache).getAsJsonObject().getAsJsonObject(Integer.toString(id));
            Gson gson = new Gson();
            return gson.fromJson(query, PricedItem.class);
        private static boolean shouldUpdate() {
            if (cache == null)
                return true;
            else if (System.currentTimeMillis() - cacheTime > HALF_HOUR)
                return true;
            return false;
        private static void fetchJSON() {
            try (BufferedReader rd = new BufferedReader(new InputStreamReader(new URL(url).openConnection().getInputStream()))) {
                StringBuilder totalString = new StringBuilder();
                String line;
                while( (line = rd.readLine()) != null) {
                cacheTime = System.currentTimeMillis();
                cache = totalString.toString();
            } catch (IOException e) {
        public class PricedItem {
            private int id, sp, buy_average, buy_quantity, sell_average, sell_quantity, overall_average, overall_quantity;
            private String name;
            private boolean members;
            public PricedItem() {}
            public int getShopPrice() {
                return sp;
            public void setShopPrice(int sp) {
                this.sp = sp;
            public int getId() {
                return id;
            public void setId(int id) {
                this.id = id;
            public int getBuyAverage() {
                return buy_average;
            public void setBuyAverage(int buyAverage) {
                this.buy_average = buyAverage;
            public int getBuyQuantity() {
                return buy_quantity;
            public void setBuyQuantity(int buy_quantity) {
                this.buy_quantity = buy_quantity;
            public int getSellAverage() {
                return sell_average;
            public void setSellAverage(int sellAverage) {
                this.sell_average = sellAverage;
            public int getSellQuantity() {
                return sell_quantity;
            public void setSellQuantity(int sellQuantity) {
                this.sell_quantity = sellQuantity;
            public int getOverallAverage() {
                return overall_average;
            public void setOverallAverage(int overallAverage) {
                this.overall_average = overallAverage;
            public int getOverallQuantity() {
                return overall_quantity;
            public void setOverallQuantity(int overallQuantity) {
                this.overall_quantity = overallQuantity;
            public String getName() {
                return name;
            public void setName(String name) {
                this.name = name;
            public boolean isMembers() {
                return members;
            public void setMembers(boolean members) {
                this.members = members;

    I've never done Json parsing so this is a learning curve, I've looked up multiple tutorials, Can anyone tell me what could make it not return anything in console?
