使用递归查找文件

package eee;

import java.util.*;
import java.io.*;

public class FileRecursionPrintDemo {
public static void main(String[] args) {
List<String> paths = new ArrayList<String>();
paths = getAllFilePaths(new File("C:\\Users\\Administrator\\Desktop\\bd_3.2.1_setup"), paths);
for (String path : paths) {
System.out.println(path);
}
}

private static List<String> getAllFilePaths(File filePath, List<String> filePaths) {
File[] files = filePath.listFiles();
if (files == null) {
return filePaths;
}
for (File f : files) {
if (f.isDirectory()) {
filePaths.add(f.getPath());
getAllFilePaths(f, filePaths);
} else {
filePaths.add(f.getPath());
}
}
return filePaths;
}
}
