Printing bufferedReader不是'；不要打印文件

我试图从一个.rtf文件打印，但似乎我的if语句被破坏了。似乎分割不起作用，因为如果我输入一个打印状态，输出只是作为第一行打印出来，它告诉用户他们正在搜索哪首歌，然后是未格式化的歌词。除此之外，代码只是在while循环中循环。当它点击

if（line.contains（song））{

时，似乎找不到歌曲。现在，我只是在硬编码文件的位置，但当我让它工作时，我会让该方法使用用户输入

任何帮助都将不胜感激

public static void main(String[] args){
     lyricsSearch("/Users/adam/Documents/Final/BlackDahliaMurder/", "miasma.rtf");
}

public static void lyricsSearch(String artist, String song){
    try {
        String stringSearch = song;
        // Opens the album file as a buffered reader
        BufferedReader bf = new 
        BufferedReader(new FileReader("/Users/adam/Documents/Final/BlackDahliaMurder/miasma.rtf"));

        // Let the user know what we are searching for
        System.out.println("Searching for " + song + "...");

        // Loop through each line, parsing.
        String line;

        while (( line = bf.readLine()) != null){
            System.out.println(line);
            if (line.contains(song)){
                String[] songInfo = line.split("\\|");
                System.out.println(Arrays.toString(songInfo));
            }       
        }
        bf.close();
    }
    catch (IOException e) {
        System.out.println("IO Error Occurred: " + e.toString());
    }
}

看着

lyricsSearch

的签名，你似乎在寻找一首名为“miasma.rtf”的歌曲——我想这不是你的本意

否则，代码看起来很好。

文件组织必须正确。相册上的所有歌曲都在一个文件中。歌曲必须以管道开头，每行必须以另一管道结尾。关键是文件中不能有任何换行符

当您在纯文本.txt文件而不是.rtf文件上使用它时，代码是否工作？它工作得更好，因为反斜杠消失了，但是如果我将代码保持在上面的状态，整个文件将被打印出来，而不是停在|处。如果我将其更改为if（line.toLowerCase（）.contains（song））{`它只打印带有歌曲名称的文件的一行。文件的组织方式如下“|歌曲名称：歌词| |其他歌曲名称：歌词|”。我实际上是在文件中查找那首歌。后来我将其更改为.txt，因为它没有打印出\where.rtf。问题是，split找不到我的分隔符。如果我更改为this

If（line.toLowerCase（）.contains（song））{

，它只打印其中包含歌曲标题的一行。txt文件是这样组织的“|歌曲名称：歌词| |其他歌曲名称：歌词|”。
