### Question:
JobQueueBatchFile implements Serializable { @Override public boolean equals(Object o) { if (this == o) return true; if (!(o instanceof JobQueueBatchFile)) return false; JobQueueBatchFile that = (JobQueueBatchFile) o; return jobQueueBatchFileID.equals(that.jobQueueBatchFileID) && jobID.equals(that.jobID); } JobQueueBatchFile();  JobQueueBatchFile(UUID jobID, UUID batchID, ResourceType resourceType, int sequence, int count); static String formOutputFileName(UUID batchID, ResourceType resourceType, int sequence); JobQueueBatchFileID getJobQueueBatchFileID(); UUID getBatchID(); UUID getJobID(); ResourceType getResourceType(); int getSequence(); String getFileName(); int getCount(); void appendCount(int count); byte[] getChecksum(); void setChecksum(byte[] checksum); long getFileLength(); void setFileLength(long fileLength); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString(); static final long serialVersionUID; }### Answer:
@Test void testEqual() { final var jobID = UUID.randomUUID(); final var batchID = UUID.randomUUID(); final var a = new JobQueueBatchFile(jobID, batchID, ResourceType.Patient, 0, 1); final var b = new JobQueueBatchFile(jobID, batchID, ResourceType.Patient, 0, 1); final var c = new JobQueueBatchFile(jobID, batchID, ResourceType.ExplanationOfBenefit, 0, 1); assertTrue(a.equals(b), "expected a to equal b"); assertFalse(a.equals(c), "expected a to not equal c"); assertTrue(a.equals(a)); }
