i have two lists based on other objects.
List<Emyployee> emyployeeList;
List<Display> displayEmployeeList;
both of them have the id's of the employees, but the second list only have a few of them. I want to filter the employeeList that i have all id's that arent in the displayEmployeeList.
how can i do that?
If
displayEmployeeList
has many items you can find useful to create a kind of index (like that of RDBMS):
