Answer 1

Assuming you want all the audit log values from all the keys in one list, sorted by modifiedDate :

If your object is LinkedHashMap<String, List<AuditLogs>> map :

List<AuditLog> sortedAuditLogs = map
   .values()
   .stream()
   .flatMap(List::stream)
   .sorted(Comparator.comparing(AuditLog::modifiedDate))
   .collect(Collectors.toList());
