java - Get Inner Json String Data from Main Json String using Gson -

i using gson parse data json string. working fine.
now, main json string contains inner json string , want inner json string's data. how ?

check json string:

[{"question":"are inclined to:","qid":"2","options":[{"option":"argue or debate issues","optionid":"4"},{"option":"avoid arguments","optionid":"5"},{"option":"swutch topics","optionid":"6"}]}] 

here, want value of "options".

sample code below :

    primarytest[] testlist = gson.fromjson(result, primarytest[].class); // result json string.     list<primarytest> lsttest = arrays.aslist(testlist);     primarytest objtest = lsttest.get(0);     string question = objtest.getquestion(); 

here, getting question value don't know how options value. if using same method giving error : invalid json data. primarytest.java code :

public class primarytest {      private string question;      public primarytest(string question) {         this.question = question;     }      public void setquestion(string question) {         this.question = question;     }      public string getquestion() {         return this.question;     } } 

write class include parameter json string contain can directly parse string class object.
primarytest class should contain following members :

public class primarytest {       private string question;       private int qid;       private list<option> options;        //getter , setter methods here }   

and option class contain members shown below :

public class option{      private string option;      private int optionid;       // getter , setter methods }     

now parse json string in primarytest class , options list getter method of class.

below test code :

primarytest[] response = gson.fromjson(json, primarytest[].class); list<primarytest> lsttest = arrays.aslist(response); primarytest objtest = lsttest.get(0);  list<option> options = objtest.getoptions(); for(option option : options){     system.out.println(option.getoption()); }
