### Question:
BaseItem { @Override public boolean equals(Object other) { if (other == null) { return false; } if (this.getClass().equals(other.getClass())) { BaseItem i = (BaseItem) other; return this.partitionKey.equals(i.partitionKey) && this.sortKey.equals(i.sortKey); } return false; } BaseItem(String partitionKey, String sortKey); Map<String, AttributeValue> toItem(); static String partitionKeyName(); static String sortKeyName(); AttributeValue partitionKey(); AttributeValue sortKey(); @Override boolean equals(Object other); @Override int hashCode(); @Override String toString();  }### Answer:
@Test void testEqualsWithNull() { assertFalse(PointerItem.generate().equals(null)); }
