How to get objects from List

Question

i have a Map like

Map <String, List<Object>> timeSerisData

which contains two lists one is headerList and another is dataList but internally dataList contains another Objects, means my dataList is list of Objects. So now i am getting that headerList and dataList like this:

@PostMapping("/doExportData")
@Timed
public void doExportData(@Valid @RequestBody Map <String, List<Object>> 
timeSerisData){
    List<Object> headerList = new ArrayList<>();
    List<Object> dataList = new ArrayList<>();
            for(Map.Entry<String, List<Object>> entry : 
            timeSerisData.entrySet()) {

        if(entry.getKey() == "headerData") {

            headerList = entry.getValue();
            System.out.println("headerlist"+headerList);

        }else {

            if(entry.getKey() == "dataList") {

                dataList = entry.getValue();
                System.out.println("data list"+dataList);
            }

        }

    }
}

In above code in dataList i am getting list which contains two objects like this:[{Ticker=GSU,Name=Revenu,Year=2015, dataList=[1,2,3,4,5,6]}, {Ticker=GSU, Name=Gross,Year=2018, dataList=[7,8,9,10,11,12]}]

Now i want to get the values of this dataList and want to set that in pojo class. So how to get those values.

you probably do not want to compare strings using the ```==``` operator. Instead I think you want to use the ```String.equals(otherString)``` method of the String class. See https://stackoverflow.com/questions/7520432/what-is-the-difference-between-vs-equals-in-java — luksch, Apr 14 '18 at 15:31
Do you want to dynamically create a pojo class, or is your dataList of a defined format and you can define the structure of that pojo class in advance? — luksch, Apr 14 '18 at 15:37
