從一個URL讀取並存儲在一個ArrayList中的JAVA

Question

我試圖從下面的URL中讀取似乎工作，但當我嘗試將其存儲在ArrayList它給我一個錯誤。有什麼想法導致錯誤？

public abstract class ItemList implements ItemListInterface{ 

private static String inputLine; 
private static ArrayList<String> wordArray; 

public static void main(String[] args) throws Exception { 
    URL wordList = new URL("http://dl.dropbox.com/u/18678304/2011/BSc2/phrases.txt"); 
    BufferedReader in = new BufferedReader(
      new InputStreamReader(
        wordList.openStream())); 



    while ((inputLine = in.readLine()) != null){ 
     System.out.println(inputLine); 
     wordArray.add(inputLine); 
    } 
    in.close(); 
    } 
}

你忘了實例化ArrayList<String>。
