  public class TestWalkFileTree 
      public static void main(String[] args) throws IOException 
          deleteMoreDirectory();
      
       /**
       * 删除多级目录
       * */
      private static void deleteMoreDirectory() throws IOException 
          Files.walkFileTree(Paths.get("E:\\\\apache-tomcat-8.5.78-副本"), new SimpleFileVisitor<Path>() 
              //进入文件夹之前
              @Override
              public FileVisitResult preVisitDirectory(Path dir, BasicFileAttributes attrs) throws IOException 
                  System.out.println("进入文件夹===>"+dir);
                  return super.preVisitDirectory(dir, attrs);
              
              //遍历文件
              @Override
              public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) throws IOException 
                  Files.delete(file);
                  return super.visitFile(file, attrs);
              
              //进入文件夹之后
              @Override
              public FileVisitResult postVisitDirectory(Path dir, IOException exc) throws IOException 
                  System.out.println("退出文件夹===>"+dir);
                  Files.delete(dir);
                  return super.postVisitDirectory(dir, exc);
              
          );
