Java中输入输出文件流操作

输入流（字符流）：

public class ReadTreeUtil {
	
	public static List<String> readFile(String path) throws IOException{
		File file = new File(path);
        InputStreamReader reader = null;
        BufferedReader br = null;
        List<String> resultList = new LinkedList<String>();
		try {
			reader = new InputStreamReader(new FileInputStream(file));
			br = new BufferedReader(reader);
	        String line = ""; 
	        while ((line = br.readLine()) != null) {
	            resultList.add(line);
	        }
		} catch (IOException e) {
			e.printStackTrace();
		} finally{
			br.close();
			reader.close();
		}
		return resultList;
	}
}
