A bus route is represented by using a list of all bus stops on that route from source to destination inclusive. For example, the bus route connecting Amman and Sult cities is a list of the following main bus stops: Amman, Swaileh, Beer-Albahsa, and Sult. Each route is a given a unique integer identification number. Write an ADT Route representing a bus route which should satisfy the following specifications:

1. [2] Immutable. 2. [2] Hides the abstraction barrier using a makeRoute method in the interface. 3. [3] Re-implements toString, equals, and hashCode. 4. [2] Provides a method interset which takes a Route object and returns a List of all shared bus stops. 5. [4] Demonstrate your solution by a. Create a route ID = 15, from Amman to Al-Sult, bus stops = [Shamal, Dakhliyya, Jordan University, Beer-Albahsa, Sult]. b. Create a route ID = 20, from Raghadan to Jordan University, bus stops = [Raghadan, Dakhliyya, Jordan University]. c. Print the route using toString method formatted as follows: ID: nn, Bus Stops: stop1, stop2, ..., last stop. d. Use the intersect method to find the shared bus stops of routs 15 and 20, and print these stops.
