如何删除目录？

解决方法

下面的例子如何通过使用File类的dir.isDirectory()，dir.list()和deleteDir()方法删除文件后删除目录。 

import java.io.File;

public class Main {
   public static void main(String[] argv) throws Exception {
      deleteDir(new File("c:\temp"));
   }
   public static boolean deleteDir(File dir) {
      if (dir.isDirectory()) {
         String[] children = dir.list();
         for (int i = 0; i < children.length; i++) {
            boolean success = deleteDir
            (new File(dir, children[i]));
            if (!success) {
               return false;
            }
         }
      }
      return dir.delete();
      System.out.println("The directory is deleted.");
  }
}

结果

上面的代码示例将产生以下结果。

The directory is deleted.
