Transform a List from a type into another type List using Guava. Practical example.

Guava Transform Function Example

final List<State> states = new ArrayList<State>();
 
final int n = 10;

for (int i = 0; i < n; i++) {
    final State state = new State(i, DeliveryReceiptState.ACCEPTD);
    states.add(state);
}
 
final List<Status<DeliveryReceiptState>> statuses = Lists.transform(
        states, new Function<State, Status<DeliveryReceiptState>>() {
            @Override
            public Status<DeliveryReceiptState> apply(final State input) {
 
                final Status<DeliveryReceiptState> status = new Status<DeliveryReceiptState>(
                        input.getId(), input.getDeliveryReceiptState());
 
                return status;
            }
        });
 
for (final Status<DeliveryReceiptState> status : statuses) {
    System.out.println(status);
}
