递归删除目录就常见了，随便网上搜了一个过来，见下面

import java.io.File;   
  
class DeleteDir {   
  public static void main(String args[]) {   
    deleteDirectory(new File(args[0]));   
  }   
  
  static public boolean deleteDirectory(File path) {   
    if( path.exists() ) {   
      File[] files = path.listFiles();   
      for(int i=0; i<files.length; i++) {   
         if(files[i].isDirectory()) {   
           deleteDirectory(files[i]);   
         }   
         else {   
           files[i].delete();   
         }   
      }   
    }   
    return( path.delete() );   
  }   
}  

非递归的还真没写过。。随便写了一个。仅供参考

import java.io.File;   
import java.util.ArrayList;   
import java.util.List;   
  
  
public class Delete {   
       
    public static void main(String[] args)   
    {   
        File deletePath = new File("你要删除的目录位置");   
        List<String> deleteList = new ArrayList<String>();   
        deleteList.add(deletePath.getPath());   
        while(deleteList.size()>0)   
        {   
            int i = deleteList.size()-1;   
            String currentPath = deleteList.get(i);   
            File[] files = (new File(currentPath)).listFiles();   
            if (files.length == 0) {   
                (new File(currentPath)).delete();   
                deleteList.remove(i);   
            }else {   
                for (int k = 0; k < files.length; k++)    
                {   
                    if(files[k].isDirectory())   
                    {   
                        System.out.println(files[k].getPath());   
                        deleteList.add(files[k].getPath());   
                    }   
                    else  
                    {   
                        System.out.println(files[k].getName());   
                        files[k].delete();   
                    }   
                }   
            }   
        }   
    }   
}
