The Main class, ITrip interface, and SimpleTrip class have been provided for you. The remaining classes you will have to complete on your own. The Builder is responsible for building your trip by creating several ComplexTrip and SimpleTrip objects and connecting them. Your trip should start at Home and then visit North Adams and Pittsfield. While in North Adams you will visit MASSMoCA, with a stop at the Lewitt Exhibit and the Cafe, and then you will check out MCLA. While in Pittsfield you will visit the Science Museum and then catch a Baseball Game. When your program is working correctly, your program should produce the following output: Visiting Home Visiting North Adams Visiting MASSMoCA Visiting Lewitt Exhibit Visiting Cafe Visiting MCLA Visiting Pittsfield Visiting Science Museum Visiting Baseball Game
