How to get the item ID in vaadin

Good day everyone! I have a HierarchicalContainer below: 

contFinalGrade= new HierarchicalContainer();
        contFinalGrade.addContainerProperty("index", Integer.class, 0);
        contFinalGrade.addContainerProperty("subCode", String.class, "");
        contFinalGrade.addContainerProperty("courseId", String.class, "");
        contFinalGrade.addContainerProperty("parentCourseId", String.class, "");
        contFinalGrade.addContainerProperty("subName", String.class, "");
        contFinalGrade.addContainerProperty("term", String.class, "");
        contFinalGrade.addContainerProperty("studyPoints", BigDecimal.class, null);
        contFinalGrade.addContainerProperty("grade", String.class, "");

and I add items by using the code below: 

Item newItem = contFinalGrade.getItem(contFinalGrade.addItem());

I'm wondering how to get the itemId using parentCourseId. I need to get it because I need to set the parent of some items. Thanks!

Maybe this is what you are looking for: 

List<Object> id = new ArrayList<Object>();

List<Item> newItem=new ArrayList<Item>();

//Do this on a button click or something maybe  
id.add(contFinalGrade.addItem()); 

//Create Items with those ids and get your property
for(int i=0;i<id.size();i++){
newItem.add(contFinalGrade.getItem(id.get(i)));

newItem.get(i).getItemProperty("parentCourseId");
