Document Summary

Both socialist and liberals agree that people are born free and equal. Freedom and equality should be both instrument and end of our existence. Freedom and equality should be a reality of everyday life. Freedom and equality in liberal thought is formal. In reality we know some people are freer than other, and there is inequality. Socialists would argue that we must go beyond the formal nature in equality. Private property creates the inequality, he possesses . Main culprit is private property, it creates exclusion. Economic inequalities creates exploitation, people will be paid to work for others. Economic exploitation will create real inequality, pave the way for political domination. Few who owns things will seek to dominate the power over many. Socialism will be an improved version of liberalism. Inequality creates class conflict: state appropriation of property, social appropriation of private property. Behind each ideology, there is a specific social force.

Programming Writing Montreal Maps In the following questions, you will write classes that allow one to suggest a route to get from one point to another on a metro or train line. Note that for all of these questions, we will make the simplifying assumption that the earth is flat and that everything resides in 2 dimensions. (There were metros before Columbus and Galileo, right?) 6. Write a class MetroStation in which you define a new type MetroStation. (10 points) A MetroStation is defined to have the following private properties: • String name This represents the name of the metro station (e.g. Atwater, McGill, etc) • double xPosition This represents the x location of the metro station. • double y Position This represents the y location of the metro station. An MetroStation object should have the following public methods/behaviors defined on it. • A constructor that takes as input a String stationName, a double x, and a double y. The constructor should initialize the properties name, xPosition, and yPosition to these three values respectively • A method getName() which returns the name of the Metrostation. • A method get XPosition () which returns the x location of the Metrostation • A method get Position () which returns the y location of the Metrostation • A method equals (Metrostation other) which returns a boolean representing whether the name property of the this MetroStation is equal to the name property of other.

X. Write a da Subway system in which you define a new type Subway System A Subway Systemen of a private ArrayList lines. No methasoher than the constructed the addline method should modify this array list. Your class should have the following co-static methods (25 points) • Write a c tor Subway system that takes thing asing and initializes the private property lines to be an empty mysl • Write a method adine which takes as input a MetroLine newline and acknowline to the array lest lines. The mathed should retun void • Write a method got Distance Travelled which takes as in ArrayList path and returns a double representing the tual distance travelled or a paththalpos from the first Metrostation in the anaylist, to the Metrostation to the third til the cod of the array listHe cach Metrostation along the joy the calculate the distance between the Metrostation and the prices. If the ArrayList Metrostation path is less than 2 vales, y mesh shox return On You may the wale path issul For m e, if the ArrayList Metrostation path five Metrostation you code calculate the sum of the distance between the fin d ing the second third the third and fourth, and lastly the fourth and final stations. Hint: To calculate the distance between two points, you can use a method defined in the appendix in the Maputilities class . Write a method findNearest Station which takes as input a double x and a double y ad the Metrostation which is nearest to the x and y. To do this, it should leather all the Metrostations of all the Metrotines inside of this lines and find the Metro Station that is the smallest distance away. You can use the same appendix method as in the precis i on You may assume that there is a leadine MetroLine defined in the property lines. You may also assume that every MetroLine in lines has at least one Metrostation in Hint There is no method such as getAll Station defined a Metrotine ohjeet. This is since providing this method would rewal a lot about the implementation of the Metrolines and would differ depending on the kind of collectice you are using to store it. However, you can simulate this art of method by using the get PirstStop () and get Next Stop () methods to access every entry of the AmyList. Remember the condition that will cause getNext Stop (to be null • A method qet Neighboringstations which takes input a Metrostation station and re- turns an ArrayList The Arrayut Metrostation whild consist of all nephring stations to station possibly many if the station in ce may lines). P erample, if statice is the 3rd stop on the blue line, the 6th stop on the red line, and the stop on the green line, then the mothed should return an ArrayList

7. Write a class MetroLine in which you define a new type MetroLine (10 points) A MetroLine is defined to have the following private properties: • A String representing the colour of the line (e.g. blue, red, green, etc. No numbers. It's Montreal, not Manhattan!) • A collection of MetroStation This collection can be either a built in array, an ArrayList, or any other kind of collection you feel would satisfy the requirements of the class. The collection must be able to define an ordering from "beginning" to "end" of the MetroLine. It does not matter which part you consider the beginning and which part is the "end" as long as it is consistent. (We recommend using ArrayList but you are free to do otherwise if you feel it will be casier.) A MetroLine should have the following methods defined: • A constructor which takes nothing as input and performs any initialization necessary to maintain your collection of stations. • A method addstation which takes as input a MetroStation and adds it to the end of your collection. The method can assume the station is not already part of the collection and should return void. Note that the order the MetroStations are added is the same as the path the trains will travel on (or it could be the reverse path as well). • A method hasStation which takes as input a MetroStation and returns a boolean representing whether the metro line has a MetroStation with the same name or not. A method get LineColour which returns the colour of the line. • A method get First Stop which returns the MetroStation representing the first stop of the metro line. If there is no such station (ic, if the collection of MetroStation is empty), your method should return null. • A method get PriorStop which takes as input a MetroStation and returns the stop prior to the MetroStation passed as input. You may assume that the MetroStation passed as input is indeed in the collection of MetroStations If the current station is the first stop on the MetroLine then this method should return null. You may assume that there are no "loops" in the MetroLine That is, no station is present on the same line twice. A method getNext Stop which takes as input a MetroStation and returns the stop after the MetroStation passed as input. You may assume that the Metrostation passed as input is indeed in the collection of Metrostations. If the current station is the last stop on the MetroLine, then this method should return null. You may assume that there are no "loops" in the MetroLine That is, no station is present on the same line twice. For the above methods, you may assume that there is no aliasing issue. That is to say, you can use == to compare the references, or if you are using a type such as ArrayList to maintain your list of stations, you can use the indexOf or contains method defined on an ArrayList.
