Java问题readline？

       你的源码代码已经报错了，这个是源码调试 jar 源码按行读取文件。InputStream inputStream = getClass().getClassLoader().getResourceAsStream("test.txt");

       StringBuilder resultStringBuilder = new StringBuilder();

       try (BufferedReader br

        = new BufferedReader(new InputStreamReader(inputStream))) {

        String line;

        while ((line = br.readLine()) != null) {

        resultStringBuilder.append(line).append("\n");

        }

       }

       System.out.println(resultStringBuilder.toString());
