递归小片段 - 咖啡岛

再递归，递归递归，不断递归。。。。。

import java.io.*;

public class TestList

{

public static void main(String[] args)

{

File f = new File("G:/JAVA");

tree(f,0);

}

public static void tree(File f, int level)

{

String pre = "";

for(int i = 0; i<level ; i++)

{

pre += " ";

}

File[] childs = f.listFiles();

for(int i = 0; i<childs.length; i++)

{

System.out.println(pre + childs[i].getName());

if(childs[i].isDirectory())

{

tree(childs[i], level + 1);

}
