关于IOsystem reader里用split方法读取的问题？

Question

老师留作业，要扫描一个文件并且将文件中的单词逐个添加进一个List<String>里去。那个文件每个单词占一行，我想用 .add(split("\n")[i])这个方法在一个循环里实现，但是我发现在\n处分割只能把第一个元素添加进List里，之后的全部没有。我用打印了一下split("\n").length，发现长度只有一。是因为read的扫描器只能扫描一行吗？

后面是代码，求教，谢谢！

public class WordFisher 
{
	public HashMap<String, Integer> vocabulary; 
	private List<String> stopwords;// (to be instantiated as an ArrayList)
	private String inputTextFile; 
	private String stopwordsFile; 
	
	public WordFisher(String inputTextFile, String stopwordsFile) throws IOException
	{
		this.inputTextFile = inputTextFile;
		this.stopwordsFile = stopwordsFile;
		stopwords = new LinkedList<String>();
		getStopwords();
	}
	
	private void getStopwords() throws IOException
	{
		try 
		{
			BufferedReader input = new BufferedReader(new FileReader(stopwordsFile));
			String read = input.readLine();
			int i = 0;
			String[] string = read.split("n");
			while(i < string.length)
			{
				stopwords.add(string[i]);
				i++;	
			}
			input.close();
			
			for(int k = 0; k < stopwords.size(); k++)
			{
				System.out.println(stopwords.get(k));
			}
		} 
		catch (FileNotFoundException e) 
		{
			// TODO Auto-generated catch block
			e.printStackTrace();
		}	
	}
}

`input.readLine()` 这个方法就是读取一行的数据,

而你文件每个单词一行, 应该按下面的来

String line;
while((line = input.readLine()) != null) {
    // do something with line
}
