java - 如何解决 “no such a directory or file”的错误？

Question

我有这个简单的代码，但是当我运行时，得到的错误不是这样的目录或文件!我怎么解决我尝试了许多都不起作用的方法!有人可以帮忙吗？

public static void main(String [] args){

    String songA = ("res/raw/canon_d_major.wav");
    String songB = ("res/raw/canon_d_major.wav");

    Wave waveA = new Wave(songA);
    Wave waveB = new Wave(songB);

    String recordedClip = ("res/raw/cock_a.1.wav");
    Wave waveRec = new Wave(recordedClip);

    FingerprintSimilarity similarity1, similarity2;

    similarity1= waveA.getFingerprintSimilarity(waveRec);

    System.out.println("clip is found at " + 
    similarity.getsetMostSimilarTimePosition() + "s in " + songA + 
    " with similarity " + similarity.getSimilarity());

    similarity2 = waveB.getFingerprintSimilarity(waveRec);

    System.out.println("clip is found at " + 
    similarity.getsetMostSimilarTimePosition() + "s in " + songB + 
    " with similarity " + similarity.getSimilarity());

}

Answer 1

File fileName = new File('path/to/file');不会在硬盘上创建文件。它是Java中唯一的新File对象，它指向您在构造函数中设置的目录。这样说来，如果在执行代码时cock_a.wav不存在，则不会实际创建它。

使用这个-> Java's createNewFile() - will it also create directories?

如果在此处发布目录结构，也可能会有所帮助。
