    Default How to get an Array of US cities?

    Is there a way in my preferred JAVA IDE (Eclipse/Netbeans) in which i can construct an array of US Cities. I'm creating a Tree in which the user can select a runnable server. So in this case, the user will click on "Servers", then down to "United States", then a whooooolllleeeee bunch of United States cities will appear. I did it with the UK cities with no problem.
    String[] ukCities = {"Bath", "Birmingham", "Bradford", "Brighton & Hove", 
    				"Bristol", "Cambridge", "Canterbury", "Carlisle", "Chelmsford",
    				"Chester", "Chickester", "Coventry", "Derby", "Durham", "Ely", "Exeter",
    				"Gloucester", "Hereford", "Kingston upon Hill", "Lancaster", "Leeds", "Leicester",
    				"Lichfield", "Lincoln", "Liverpool", "City of London", "Manchester", 
    				"Newcastle upon Tyne", "Norwich", "Nottingham", "Oxford", "Peterborough", "Plymouth", 
    				"Preston", "Ripon", "Salford", "Salisbury", "Sheffield", "Southampton", "St Albans",
    				"Stoke-on-Trent", "Sunderland", "Truro", "Wakefield", "Wells", "City of Westminister", 
    				"Wolverhampton", "Worcester", "York"};
     
    DefaultMutableTreeNode[] ukNode = new DefaultMutableTreeNode[50];
    		for(int i = 0; i < 49; i++) {
    			ukNode[i] = new DefaultMutableTreeNode(new ServerInfo (ukCities[i], i, selectedServers.contains(i)));
    			ukRootBranch.add(ukNode[i]);
    		}
    And baaaaammm, it works. I want something similar to this, but it's just waaaaay to time consuming adding over 200+ cities and I really don't want to spend my whole day typing out each individual city from a wikipeda page... Maybe there is something Java already provides for us, and I just don't know what?

    Any help, would be greatly approved of. For now, I will go and make myself a cup of tea and enjoy some rich tea biscuits...

    Do you have them in a file somewhere? Just load them from that instead. I'm sure you can find a file online.

    Cheers, I've used that way. Didn't realise I could do it from a text file, added them now. Cheers Kevin!

    Also, when you are trying to populate a file with information like this, try not to do it manually. There are webservices available for things like this. In fact, the SBA (US Small Business Association) has a public one for this exact purpose.
    Here is a link to their webservice documentation: U.S. City and County Web Data API | SBA.gov

    To query the webservice from Java, you would just open a url connection to the desired information and parse it as an XML file or a JSON message. So, if you wanted all the cities in Florida, you would open a connection to:
    http://api.sba.gov/geodata/city_coun...or_state_of/FL
    You can view that page in your browser to see the result it provides.
