Salesforce Json Deserialization Concept

public class testingarryfuction {

 
   public StateInfodetails StateInfodetailswraper{get;set;}
   
    public  testingarryfuction (){
    
    
     string teststring ='{ "sucess":1,"data":{"Stateidselected":"2","StateInfodetails":{"stateName": "Andrapradesh","value": "apx" ,"rating":5}}}';

    Map<String, Object> maptest =   (Map<String, Object>) JSON.deserializeUntyped(teststring);
          system.debug('mapped and deserialized data is::'+maptest);
          
           
      Object ob = (Object)maptest.get('data');    
       system.debug('get data is::'+ob);
       
     String srlze  = System.JSON.serialize(ob); 
      system.debug('again deserailized is ::'+srlze );
      
       StateInfodetailswraper = (StateInfodetails)System.JSON.deserialize(srlze,StateInfodetails.class);
     system.debug('deserilize using the wrapperclass::::::'+StateInfodetailswraper );
      system.debug(StateInfodetailswraper.stateName);
    }
    
    
     //this is a wrapper class 
     public class StateInfodetails{
     public string stateName{get;set;}
     public string  value{get;set;}
     public integer rating{get;set;}
    
   }

   
   
   
  
}

Hi Deepika,

I've gone through your code and inside your code you must do below changes:

1.Remove the "data " from inside the teststring and it will work fine:
(i.e.)
string teststring ='{ "sucess":1,{"Stateidselected":"2","StateInfodetails":{"stateName": "Andrapradesh","value": "apx" ,"rating":5}}};



I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.

Thanks and Regards,
