dear sir/madam iam contacting you regarding a java problem which i have come across. My teacher at manchester met has set a problem for us to solve but thinking his teaching is excellent and everyone understands him wen no one does I would appreciate you helping me in this problem as it would save us from embarrassment. THE PROBLEM: Consider a simplified plan of the liverpool bus system. The system consists of a network of bus stops(at most 20) and bus lines (at most 5). Each bus stop has a unique name and each busline has a unique number. Each bus stop is connected to other bus stops by at most 3 different bus lines. Each of these bus lines connects a bus stop to exactly one other bus stop and for each bus stop and each connecting bus line it is known how many minutes the bus needs to get to the next bus stop. The objectives are to design and implement in java: 1. A representation of the bus system using suitable data structures. 2. A mechanism to go from one bus stop to a conected bus stop via a particular bus line. 3. A mechanism for searching for a connection between two given bus stops. A command line text based interface should be provided that will allow the user to issue a series of the following five commands: start: Allows to enter the current bus stop by name and resets the total journey time to zero. list: The system will show the total journey time so far, and all information on the current bus stop, that is, its name and the numbers of all outgoing bus lines. go: The system asks for the number of a busline. If the number is that of an outgoing busline, then the system finds out the busstop connected to the current bus stop and makes it the new current bus stop. If the number is not that of an outgoing bus line, then the system will indicate this by a message , but make no other changes. search: The system asks for the name of a bus stop. The system will then indicate whether there is a way to get to this bus stop from the current bus stop, but makes no other changes. exit: Stops and exits the system.
