### Question:
Offset implements NullaryPredicate, Predicate<Object>,
        BinaryPredicate<Object, Object> { @Override public boolean equals(Object obj) { if (obj == this) { return true; } if (!(obj instanceof Offset)) { return false; } Offset other = (Offset) obj; return other.min == min; } Offset(int count); boolean test(); boolean test(Object obj); boolean test(Object a, Object b); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void testEquals() { Offset offset = new Offset(1); assertObjectsAreEqual(new Offset(1), offset); assertObjectsAreNotEqual(new Offset(2), offset); assertTrue(!offset.equals(null)); }
