### Question:
Position { static boolean intersect(Disk firstPoint, Disk secondPoint) { double a = Math.abs(firstPoint.getPosition().y - secondPoint.getPosition().y); double b = Math.abs(firstPoint.getPosition().x - secondPoint.getPosition().x); return (Math.sqrt(a * a + b * b) <= firstPoint.getRadius() + secondPoint.getRadius() - 0.001); } Position(double x, double y, double z);  public Double x; public Double y; public Double z; }### Answer:
@Test void intersectTest() { boolean result = Position.intersect(disk1, disk2); assertTrue(result); }
