Adding the ArrayList<StudentBean> values to HashMap<Integer, StudentBean>

Question

I have a List:

List<StudentBean> resultList

StudentBean has something like with getters and setters:

{ Integer StudentId, String StudentName, String Section}.

I have a map with values: Map<Integer, StudentBean> orginialStudentDetails

Now I want to add/replace the values from resultList to orginialStudentDetails, how can I achieve that?

Tried:

for (Map.Entry<Integer, StudentBean> entry : resultList .size()){
     orginialStudentDetails.put(entry.getKey(), resultList );
}

Answer 1

In addition to Joxtacy's correct approach:

resultList.forEach(s -> originalStudentDetails.put(s.getStudentId(), s));
