Document Summary

Behaviors that can be performed on or by the object. Then when you create a new object you can change the properties. Do not need to instantiate class to use them. Don"t need to create new object references to use static methods. Don"t want outside classes access to private properties. Process of creating an object: instantiating a class. Private = can either be accessed or evoked by other methods of the same class. Int[] a = new int[2] a. length (length is a public variable) Variable x, x. make x refers to variable make. Lower classes inherit properties from higher java classes. Can override a method from the parent class.

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.
