Filter an object list based on Integerlist [closed]

Answer 1

First, you need to change subscription to employee.

Either change your ID list to a list of Strings and populate accordingly or do something like this:

List<Employee> filteredList;
filteredList = employeeList.stream()
     .filter(employee -> ids.contains(Integer.parseInt(employee.getId())))
     .collect(Collectors.toList());

Other options include changing your Employee class to use an int as an id.
