用list()列出当前路径下所用文件和路径 编译出错 上次没发全看错了

import java.io.File;

import java.io.IOException;

 class Filetest

{
public static void main (String[] args) throws IOException

{ File file= new File(" . ");

         System.out.println(file.getName());

         System.out.println(file.getParent());

         System.out.println(file.getAbsoluteFile());

         System.out.println("file.getAbsolutefile().getParent()");

         File tmpFile = File.createTempFile("aaa",".txt",file);

         tmpFile.deleteOnExit();

         File newFile = new File(System.currentTimeMillis() + "");

         System.out.println("newFile对象是否存在: " + newFile.exists());


         newFile.createNewFile();

         newFile.mkdir();

         String[]  fileList = file.list();

         System.out.println("====当前路径下所有文件和路径如下====");

         for (String  filename:filelist)
     {   

          System.out.println("fileName");

      }

         File[]  roots =  File.listRoots();

         System.out.println("====系统所有根路径如下====");

         for  (File  root : roots)
       {

         System.out.println(root);

        }

       }

   }
    编译时出错

d:\>javac  -d .1.java
1.java:41:错误：找不到符号 
     for(String  filename:filelist)

        符号：变量filelist 
        位置：类filetest
         1个错误

filelist 变量定义的是 fileList ,大写的 L。
相信编译器吧，机器比人实诚呢。

        for (String  filename:fileList)
        {

            System.out.println("fileName");

        }

System.out.println("fileName");
->
System.out.println(filename);

for (String filename:filelist)
->
for (String filename:fileList)

for (String filename:fileList)
