关于迭代的简单应用:查看文件夹的路径

public class FileTest2 {

private static String URL_PATH = "E:\\dzfpfile\\dzfpftp\\FP\\";

public static void main(String[] args) {

File file = new File(URL_PATH);

if(file.isDirectory()){
File[] files = file.listFiles();

for (File file2 : files) {
if(file2.isDirectory()){
File[] files2 = file2.listFiles();
for (File file3 : files2) {
System.out.println(file3);
}
}
}
}
}
}
