### Question:
LastAddConfirmedUpdateNotification implements Recyclable { @Override public void recycle() { this.lastAddConfirmed = -1L; this.timestamp = -1L; handle.recycle(this); } LastAddConfirmedUpdateNotification(Handle<LastAddConfirmedUpdateNotification> handle); static LastAddConfirmedUpdateNotification of(long lastAddConfirmed); @Override void recycle(); static final Function<Long, LastAddConfirmedUpdateNotification> FUNC; static final RecyclableArrayList.Recycler<Watcher<LastAddConfirmedUpdateNotification>> WATCHER_RECYCLER; }### Answer:
@Test public void testRecycle() { long lac = System.currentTimeMillis(); LastAddConfirmedUpdateNotification notification = LastAddConfirmedUpdateNotification.of(lac); notification.recycle(); assertEquals(-1L, notification.getLastAddConfirmed()); assertEquals(-1L, notification.getTimestamp()); }
