java简单列出文件夹下所有文件的方法

import Java.io.*;
public class ListFiles {
  private static String s = "";
  private static BufferedReader in = new BufferedReader(
      new InputStreamReader(System.in));
  public static void main(String[] args) {
    try {
      s = in.readLine();
      getFileList(s);
      in.close();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
  public static void getFileList(String directory) {
    File f = new File(directory);
    File[] files = f.listFiles();
    for (int i = 0; i < files.length; i++) {
      if (files[i].isFile()) {
        System.out.println("文件：" + files[i]);
      } else {
        System.out.println("目录：" + files[i]);
        // System.out.println("目录绝对地址：" + files[i].getAbsolutePath());
        getFileList(files[i].getAbsolutePath());
      }
    }
  }
}
