### Question:
Batch implements IBatch { @Override public boolean equals(Object obj) { if (this == obj) { return true; } if (!(obj instanceof Batch)) { return false; } return uuid.equals(((Batch) obj).getUuid()); } Batch(String uuid);  Batch(String uuid, String name, String group); @Override boolean equals(Object obj); String getCurrentItem(); String getCurrentTask(); Date getEndDate(); String getGroup(); long getItemCount(); String getLastMessage(); Date getLastUpdate(); String getName(); IBatchProgressMonitor getProgressMonitor(); float getProgressStatus(); List<String> getRejectedItemsId(); Date getStartDate(); String getStatus(); String getUuid(); boolean isSuccess(); void setProgressMonitor(IBatchProgressMonitor monitor); void setZombieInterval(int zombieInterval);  }### Answer:
@Test public void testEqualsObject() { Batch batch = new Batch("12345"); assertThat(batch.equals(new Batch("12345")), is(true)); assertThat(batch.equals(new Batch("54321")), is(false)); assertThat(batch.equals(null), is(false)); }
