[Java] 利用java.nio 存取檔案

存取檔案是基本的programming 技巧. 正好Java 8 出了nio package, 就試了用它將檔案當成string去存取.

private String readLineByLine(String filePath)
	{
	    StringBuilder contentBuilder = new StringBuilder();
	    try (Stream<String> stream = Files.lines(Paths.get(filePath), StandardCharsets.ISO_8859_1))
	    {
	        stream.forEach(s -> contentBuilder.append(s).append("\n"));
	    }
	    catch (IOException e)
	    {
	        e.printStackTrace();
	    }
	    return contentBuilder.toString();
	}
