希望各位大神看看，代码有点长，新手希望大家多多赐教

这个程序在eclipse上运行有错误，希望大神讲详细点，谢谢。。。

你代码编译没有报错？？？？
----------------解决方案--------------------------------------------------------
这个编译到处都是错，你怎么运行的？？？
----------------解决方案--------------------------------------------------------
你想实现什么？
----------------解决方案--------------------------------------------------------
程序代码：
String path = "E:\\Media"; //文件路径（我电脑上的，你换成上面的）
File file = new File(path);
File[] fileList = file.listFiles();
for(File filename : fileList){
System.out.println(filename); //打印文件名
}
File file = new File(path);
File[] fileList = file.listFiles();
for(File filename : fileList){
System.out.println(filename); //打印文件名
}
这段代替
TreeMap<String,String> fileList = FileName.getFile("C:\\Users\\王春晓\\Desktop\\cumcm2013problems\\B\\附件1\\");
for(String s : fileList.keySet()){
//System.out.println(s+"\t"+fileList.get(s));
FileList fileList = getFileList("C:\\Users\\王春晓\\Desktop\\cumcm2013problems\\B\\附件\\"); // get file name list from a folder
你这段代码根本编译不过。
这样你就可以读文件名了，然后自己再看看，自己哪里哟偶问题，我拷贝你代码到myeclipse上面到处是红的。都不知道你哪些变量和方法从哪里来的，自己调试下。
