### Question:
Conflict { public boolean equals(Object x) { if (x instanceof Conflict) { Conflict that = (Conflict) x; return Objects.equals(this.ancestor, that.ancestor) && Objects.equals(this.theirs, that.theirs) && Objects.equals(this.ours, that.ours) && Objects.equals(this.path, that.path); } else { return false; } } Conflict(@NonNull String path, @NonNull ObjectId ancestor, @NonNull ObjectId ours,
            @NonNull ObjectId theirs); ObjectId getAncestor(); ObjectId getOurs(); ObjectId getTheirs(); String getPath(); boolean equals(Object x); int hashCode(); String toString();  }### Answer:
@Test public void testEquals() { ObjectId id1 = ObjectId.valueOf("abc123000000000000001234567890abcdef0000"); ObjectId id2 = ObjectId.valueOf("abc123000000000000001234567890abcdef0001"); ObjectId id3 = ObjectId.valueOf("abc123000000000000001234567890abcdef0002"); ObjectId id4 = ObjectId.valueOf("abc123000000000000001234567890abcdef0003"); Conflict conflict1 = new Conflict("Points/1", id1, id2, id3); Conflict conflict2 = new Conflict("Points/2", id1, id2, id3); Conflict conflict3 = new Conflict("Points/1", id4, id2, id3); Conflict conflict4 = new Conflict("Points/1", id1, id4, id3); Conflict conflict5 = new Conflict("Points/1", id1, id2, id4); assertFalse(conflict1.equals(conflict2)); assertFalse(conflict1.equals(conflict3)); assertFalse(conflict1.equals(conflict4)); assertFalse(conflict1.equals(conflict5)); assertTrue(conflict1.equals(conflict1)); assertTrue(conflict2.equals(conflict2)); assertTrue(conflict3.equals(conflict3)); assertTrue(conflict4.equals(conflict4)); assertTrue(conflict5.equals(conflict5)); assertFalse(conflict1.equals("conflict1")); }
