how to iterate duplicate list values and set to map object in java

Hi Experts,

i am getting list of object values from db.
i have to iterate and set to map object
if the duplicate is repeated i need to verify it is already added to the map or not
if it is already added to the map then i need to check the status
if the status is delivered in first object itself. no need to update the status
if the status is inprogress or pending i need to update the status in map

public class Problem{
private String problemName;
private String status;

setters and getters...


public class ProblemDto{
private Map<String,Problem> problems;
setters and getters..

List<Object> details = dataFromDao.getproblemsData(); //getting the data from database
Map<String,Problem> resultMap= new HashMap<>();
for(Object object :detaisl){
Object[] row = (Object[])object;
final Problem problem = new Problem();
problem.setProblemName((String) row[0]);
problem.setStatus((String) row[1]);

Open in new window

details list contains duplicated problem names and status
map will not allow duplicates.but i need to update status

let suppose i am getting the values from db like

laptopproblem   pending
telephoneproblem  completed
computerproblem  inprogress
//duplicate values
laptopproblem    delivered

in map i need to check laptopproblem instead of pending i need to replace with delivered.

laptop problem   inprogress

if i got one more duplicate problemname i no need to update, if the status is delivered no need to update  if not i have to update the status

how to do can some one suggest me

maybe something like (not tested):

for(Object object :detaisl){
  Object[] row = (Object[])object;
  String key = ((String)row[0];
  Problem problem = map.get(key);

  if(problem != null){
    String currentStatus = problem.getStatus();
    String newStatus =  (String)row[1];
    if(currentStatus.equals("pending") && newStatus.equals("delivered")){
    map.put(key, problem)
