Java - order things in arraylist according to attribute

Hi, I have an arraylist, let's call it "callcenterList" in this arraylist, I will add objects of the "Call" class.

Call objects have different attributes, some of them are Status, Month, and Day (month and day when a call is received and its status).

Status can be Completed or Pending

Thus, the Call object will look like this:
call1:
Atribute1 = whatever.
Atribute2 = whatever.
Month = 3
Day = 25
Status = Pending

So here is what they needed to do:

I need to show all calls with status = Waiting and sort by date. How can i do this? If you need more information or more details, let me know. Thank!

Here is an example. Assume that it Callhas methods getStatus()and getDate(), and getDate()- Comparable(class java.util.Date).

List<Call> calls = ...
final List<Call> filteredCalls = FluentIterable.from(calls).filter(new Predicate<Call>() {
    @Override
    public boolean apply(final Call input) {
        return "pending".equals(input.getStatus());
    }
 }).toSortedList(new Comparator<Call>() {
    @Override
    public int compare(final Call firstCall, final Call secondCall) {
        return firstCall.getDate().compareTo(secondCall.getDate());
    }
 });

In Java 8, this expression becomes much more concise, and you do not need to use a third-party library.

final List<Call> filteredCalls = calls.stream()
                                .filter(c -> "pending".equals(c.getStatus()))
                                .sorted((left, right) -> left.getDate().compareTo(right.getDate()))
                                .collect(Collectors.toList());
