### Question:
LongUuid { public int getProcessId() { return (uuid[0] & 0xFF) << 8 | uuid[1] & 0xFF; } LongUuid();  LongUuid(final byte[] bytes);  LongUuid(final long value);  LongUuid(final String idsource); @Override String toString(); byte[] getBytes(); int getProcessId(); long getTimestamp(); @Override boolean equals(final Object o); @Override int hashCode(); long getLong();  }### Answer:
@Test public void testPIDField() throws Exception { final LongUuid id = new LongUuid(); assertEquals(JvmProcessId.jvmProcessId() & 0xFFFF, id.getProcessId()); }
