### Question:
ActorId extends Object implements Comparable<ActorId> { @Override public String toString() { return this.stringId; } ActorId(String id); @Override String toString(); @Override int compareTo(ActorId other); @Override int hashCode(); @Override boolean equals(Object obj); static ActorId createRandom();  }### Answer:
@Test public void getId() { String id = "123"; ActorId actorId = new ActorId(id); Assert.assertEquals(id, actorId.toString()); }
@Test public void verifyToString() { String id = "123"; ActorId actorId = new ActorId(id); Assert.assertEquals(id, actorId.toString()); }
