How to get the Object Value and add to Arraylist in Java without for loop

Question

Getting the Object value and add to Arraylist and then I have to check arraylist contains string or not.

Below is the POJO Class, finally this will get as Object

public class OrderTypeFeature{

    public OrderTypeFeature(ODataEntity entity){
        create(entity);
    }

    private String OrderType;
    private String Feature;

    public String getOrderType() {
        return OrderType;
    }

    public void setOrderType(String orderType) {
        OrderType = orderType;
    }

    public String getFeature() {
        return Feature;
    }

    public void setFeature(String feature) {
        Feature = feature;
    }

    public static ArrayList<OrderTypeFeature> getOrderTypeFeatures(String orderType){

        ArrayList<OrderTypeFeature> orderTypeFeatures = new ArrayList<>();
        ResponseObject result = new ResponseObject(ConfigManager.Status.Error);

        try {

            String resourcePath = Collections.LT_ORDERTYPEFEATURESET+"?$filter=(OrderType eq '"+ orderType +"')";

            result = DataHelper.getInstance().getEntities(resourcePath, StoreSettings.Stores.MdLV);

            if(!result.isError()){
                List<ODataEntity> entities = (List<ODataEntity>) result.Content();
                for (ODataEntity entity : entities){
                    orderTypeFeatures.add(new OrderTypeFeature(entity));
                }
            }

        }catch (Exception e){

            result.setMessage(e.getMessage());
            DliteLogger.WriteLog(OrderTypeFeature.class, AppSettings.LogLevel.Error, e.getMessage());

        }
            return orderTypeFeatures;
        }

}

You can check whether an ArrayList (or in fact any class implementing the List interface) contains an element by calling

List.contains(Object)

Have a look at the Java documentation for more information.
