最近学Java，学到了File类，感觉很好用，于是就写个程序列出我搞OI时留下的代码文件的目录树。
//By LYLtim
import java.io.File;
public class TestFile {
public static void main(String[] args) {
File f = new File("D:/Temp/LYLtim_OI");
System.out.println(f.getName());
list(f, 0);
}
static void list(File f, int lv) {
File[] childs = f.listFiles();
for (int i = 0; i < childs.length; i++) {
for (int j = 0; j < lv; j++)
System.out.print(" ┃");
if (i == childs.length - 1)
System.out.println(" ┗" + childs[i].getName());
else
System.out.println(" ┣" + childs[i].getName());
if (childs[i].isDirectory())
list(childs[i], lv + 1);
}
}
}
