java按行读取文件

　　/**
     * 按流读取文件
     * @param path
     * @return
     * @throws FileNotFoundException
     */
    public static BufferedReader openFile(final String path) throws FileNotFoundException {
        FileInputStream in = new FileInputStream(new File(path));
        BufferedReader reader = new BufferedReader(new InputStreamReader(in));

        return reader;
    }

一行一行的读取：

read.readLines();

 注意：这里返回的不是数组，而是字符串。
