how to verify json format is valid

I use Gson class in order to convert a
Json object into a java object.
If it works without any error, it means that it is a valid json format...

import com.google.gson.Gson;

public class JSONUtils {

  Gson gson = new Gson();

  public boolean isJSONValid(String jsonInString) {
      try {
          gson.fromJson(jsonInString, Object.class);   
          return true;
      } catch(com.google.gson.JsonSyntaxException e) { 
          return false;
      }
  }
}
