POHow to access non static cloned arrayList for use in static method in Java
text
Body
copied!<p>As part of an assignment Im trying to access a cloned array list from another class so I can utilize it. But when attempting to do so I get the following error "non-static method getConnections() cannot be refrenced from a static context". </p> <p>This is the code I'm using to access the cloned array. It is in the context of working out the best way to take flights from one destination to another.</p> <pre><code>public boolean determineRoute(City from, City to, ArrayList<City> flightRoute) { ArrayList<City> Connections = new ArrayList<City>(); Connections = City.getConnections(); return true; } </code></pre> <p>And this is how the code for that class begins. It does start as static but as far as i can see it should only affect the first method how can I tell java that this method should not be considered static so I can access the cloned list from the non static class??</p> <pre><code>import java.util.*; public class Lab9_Ex2_Main { //////// START-UP ///////// public static void main(String[] args) { new Lab9_Ex2_Main(); } </code></pre> <p>I have left out a lot of the code as I think it may not be right from me to put every thing up. But should you need more to get a clearer picture I will happily add more of the code.</p> <p>This is the code from another class which contains a cloned array which im attempting to access.</p> <pre><code>import java.util.*; // Class: City // Purpose: To represent a place in the world that you can fly from/to. public class City { private String name; // The name of the City private ArrayList<City> connectsWith; // Which cities are connected to this one public City(String cityName) { name = cityName; connectsWith = new ArrayList<City>(); } // Method: addConnection // Purpose: To note that you can catch a flight to the destination, from this city // Passed: // destination - The City which you can fly to. public void addConnection(City destination) { if (destination != null && destination != this) connectsWith.add(destination); } // Method: getConnections // Purpose: To retrieve a list of cities you can reach from this one. // Note: You are given a clone, (to avoid a privacy leak), and can manipulate it however // you like. E.g. you could delete elements. public ArrayList<City> getConnections() { return (ArrayList<City>) connectsWith.clone(); } public String getName() { return name; } public String toString() { return name; } } </code></pre>
