Applicable to basic data types and object types ( The object type is a field in the comparison object ).

List<AA> AAs ;// Need to sort list aggregate 
// Reverse order 
Collections.sort(AAs, (AA a, AA b) -> {
    return b.getValue().compareTo(a.getValue());
});
// Positive order 
Collections.sort(AAs, (AA a, AA b) -> {
    return a.getValue().compareTo(b.getValue());
});
