How to Scan All Mp3 Files In the Given Directory using Java?
In this article, we will discuss how to scan all mp3 files and not only from a specific path for an android media player. We will use a recursive method for scanning files. Scan all folders and sort out all mp3 files using the File and FileFilter class.
Implementation
Java
import java.io.File;import java.io.FileFilter;  // Java program for scan all mp3 files in given directory  public class Main {      public static final String C_DIRECTORY = "C:\\";      public static void main(String[] args)    {        scanAllFile(C_DIRECTORY);    }      // recursive function for scan all files in directory    public static void scanAllFile(String path)    {        File file = new File(path);          File[] files = file.listFiles();        if (files == null)            return;          for (File f : files) {              if (f.isDirectory() && f.exists()) {                try {                    scanAllFile(f.getPath());                }                catch (Exception e) {                    e.printStackTrace();                    continue;                }            }            else if (!f.isDirectory() && f.exists()) {                // using file filter                if (filter.accept(f)) {                    System.out.println(f.getName());                }            }        }    }      // file filter for sort mp3 files    static FileFilter filter = new FileFilter() {        @Override           public boolean accept(File file)        {            if (file.getName().endsWith(".mp3")                || file.getName().endsWith(".mp3")) {                return true;            }            return false;        }    };} |
Output:
