how to fetch a particular record from JSON parse

i am getting parsed data from this  
wrapperlhscount wlc = hrwdLocationHealthStatusTileController.parse(res.getBody());

my response is  
{
    "transactionSequenceId": "w465t4564hfgdys547ue54",
    "code": "200",
    "subCode": "1000",
    "status": "Success",
    "message": "OK",
    "parentCompanyId": "SWC",
    "responseData": {
        "locationHealthStatusList": [
            {
                "companyId": "SWC",
                "parentCompanyId": "SWC",
                "family": "Managed Router Services",
                "status": "Normal",
                "statusCount": 3994
            },
            {
                "companyId": "SWC",
                "parentCompanyId": "SWC",
                "family": "Managed Router Services",
                "status": "Backup Down",
                "statusCount": 39
            }
  
        ]
    }
}
I wanted to fetch statusCount from the response

HI Abhish,
The JSON Response needs to be deserialized and then assigned to a String variable.
In the context of Apex, you can define an Apex class and then deserialize the JSON string into the class. Then testData1 is just a property of the class; 
public class TestData {
    public String testData1 {get; set;}
    public String testDat2 {get; set;}
}
TestData data = (TestData) JSON.deserialize(jsonString, TestData.class);
String var1 = data.testData1;
Or you can simply deserialize the JSON string into a map using the deserializeUntyped method:  
Map<String, Object> m = (Map<String, Object>) JSON.deserializeUntyped(jsonString);
String var1 = (String) m.get('testData1');

Recommend reviewing the examples provided in below posts to get started:

hi I tried using deserializeUntyped but it is giving me error 
map <string,object> JSONbody =(map <string,object>)json.deserializeUntyped(res.getBody());
         system.debug('JSON BODY'+JSONbody);
         Map<String, Object> dim =(Map<String, Object>)JSONbody.get('responseData');
         System.debug('dim'+dim);
         for( Object o : dim) {
            Map<String, Object> castedObject = (Map<String, Object>)o;
            List<Object> sffFieldNames = o.get('locationHealthStatusList');
            for( Object o1 : sffFieldNames) {
              Map<String, Object> newCast = (Map<String, Object>)o1;
              Object acct = o1.get('statusCount');
              system.debug('statusCount'+statusCount);
            }
          }
