json - GSON not returning key name, only value (Java) -


i'm trying format string data json using gson api, shown in returnjson() method:

import com.google.gson.*; import com.google.gson.annotations.serializedname;  public class hukd {     @serializedname("title")     public string title;     @serializedname("deal url")         public string dealurl;     @serializedname("product url")         public string producturl;     @serializedname("image url")             public string imgurl;     @serializedname("description")             public string description;      @serializedname("temperature")             public string temperature;     @serializedname("ean")     public string ean;     @serializedname("price")     public string price;     @serializedname("amazon price")     public string amazonprice;     @serializedname("price difference")     public string pricedifference;     @serializedname("amazon url")     public string amazonurl;      public hukd(string title, string dealurl, string producturl, string imgurl, string description, string temperature, string ean, string price, string amazonprice, string pricedifference, string amazonurl) {         this.title = title;         this.dealurl = dealurl;         this.producturl = producturl;         this.imgurl = imgurl;         this.description = description;         this.temperature = temperature;         this.ean = ean;         this.price = price;         this.amazonprice = amazonprice;         this.pricedifference = pricedifference;         this.amazonurl = amazonurl;     }  public string returnjson(){     system.out.println("********testing objects*************");     string[] jsonbuilder = new string []{title, dealurl, producturl, imgurl, description, temperature, ean, price, amazonprice, pricedifference, amazonurl};     gson gson = new gsonbuilder().setprettyprinting().setfieldnamingpolicy(fieldnamingpolicy.upper_camel_case).create();     string json = gson.tojson(jsonbuilder );     return json; }

however, gson return value, not key:

[   "philips shm3560/10 on ear headphones £8.99 argos",   "http://www.hotukdeals.com/deals/philips-shm3560-10-headphones-8-99-from-argos-2390246?aui\u003d1063",   "http://www.hotukdeals.com/visit?m\u003d5\u0026q\u003d2390246",   "http://static.hotukdeals.com/images/threads/2390246_1.jpg",   "argos cat no- 108/7390\nhttp://www.argos.co.uk/webapp/wcs/stores/servlet/searchmobile?storeid\u003d10151\u0026catalogid\u003d25051\u0026langid\u003d110\u0026searchterm\u003d108%2f7390",   "171°",   "8712581626211",   "£8.99",   "£12.59",   "argos cheaper amazon £3.60",   "http://www.amazon.co.uk/philips-shm3560-10-pc-headset-shm3560/dp/b008fse6eu%3fsubscriptionid%3dakiailn2tpm667mbmjaq%26tag%3dgithubcomthis-21%26linkcode%3dxm2%26camp%3d2025%26creative%3d165953%26creativeasin%3db008fse6eu" ]

i've tried around adding serializedname annotation suggested in "json field naming support" section of api documentation here, i'm still not having luck. ideally, i'd json formatted so:

"title":"philips shm3560/10 on ear headphones £8.99 argos"

(and on...), i.e. key name printed specified in @serializedname annotation in field declaration.

thanks!

you not serializing object, array of strings see proper result of serialization. if want serialize object must use this:

public string returnjson(){     gson gson = new gsonbuilder().setprettyprinting().setfieldnamingpolicy(fieldnamingpolicy.upper_camel_case).create();     string json = gson.tojson(this);     return json; }
