### Question:
JmsProducerId extends JmsAbstractResourceId implements Comparable<JmsProducerId> { public long getValue() { return value; } JmsProducerId(JmsSessionId sessionId, long producerId);  JmsProducerId(JmsProducerId id);  JmsProducerId(String connectionId, long sessionId, long producerId);  JmsProducerId(String producerKey); JmsSessionId getParentId(); String getConnectionId(); long getValue(); long getSessionId(); @Override String toString(); @Override int hashCode(); @Override boolean equals(Object o); @Override int compareTo(JmsProducerId other);  }### Answer:
@Test public void testStringConstructor() { JmsProducerId id = new JmsProducerId(firstId, 1); assertNotNull(id.getValue()); assertNull(id.getProviderHint()); }
@Test public void testJmsProducerIdFromJmsSessionId() throws Exception { JmsProducerId id1 = new JmsProducerId(firstId, 1); JmsProducerId id2 = new JmsProducerId(id1); assertSame(id1.getValue(), id2.getValue()); }
