Answer 1

简单点：
        File[] flist;
        File a=new File("c:\\");
        flist=a.listFiles();
        for(int i=0;i<flist.length;i++)
           System.out.println(flist[i]);

Answer 2

String path="D:/websrc";                                         
File[] files  = (new File(path)).listFiles();                    
File temp;                                                       
for(int i=0;i<files.length;i++){                                 
for(int j=i;j<files.length;j++){                             
if(files[i].getName().compareTo(files[j].getName())>0){  
temp = files[i];                                     
files[i]=files[j];                                   
files[j]=temp;                                       
}//if//                                                  
}                                                      
}                                                                
for(int k=0;k<files.length;k++){                                 
System.out.println(files[k].getName());                      
}
