### Question:
RemoteSession implements Serializable { @Override public int hashCode() { return Objects.hash(sessionId); } @SuppressWarnings("unused") private  RemoteSession();  RemoteSession(String sessionId);  RemoteSession(String sessionId, String eventBridgeFactory,
            Map<String, String> eventBridgeParameters); @Override int hashCode(); @Override boolean equals(Object o); String getSessionId(); String getName(); void setName(String name); boolean isServerEventsEnabled(); @Override String toString(); static Collection<EventSubject> getSubjects(); String getEventBridgeFactory(); Map<String, String> getEventBridgeParameters();  }### Answer:
@Test public void testHashCode() { RemoteSession d1 = new RemoteSession("1"); RemoteSession d2 = new RemoteSession("1"); assertEquals(d1.hashCode(), d1.hashCode()); assertEquals(d1.hashCode(), d2.hashCode()); d2.setName("some name"); assertEquals(d1.hashCode(), d2.hashCode()); RemoteSession d3 = new RemoteSession("2"); assertFalse(d1.hashCode() == d3.hashCode()); }
