### Question:
Rect { boolean intersects(Rect other) { return !(this.coordinateX + this.width / 2 <= other.coordinateX - other.width / 2 || this.coordinateX - this.width / 2 >= other.coordinateX + other.width / 2 || this.coordinateY + this.height / 2 <= other.coordinateY - other.height / 2 || this.coordinateY - this.height / 2 >= other.coordinateY + other.height / 2); } Rect(double x, double y, double width, double height);   }### Answer:
@Test void intersectsTest() { var r1 = new Rect(10, 10, 20, 20); var r2 = new Rect(15, 15, 20, 20); var r3 = new Rect(50, 50, 20, 20); assertTrue(r1.intersects(r2)); assertFalse(r1.intersects(r3)); }
