以下实例演示了使用 File 类的 ofdir.isDirectory(), dir.list() 和 deleteDir() 方法在一个个删除文件后删除目录 :

/*

 Main.java
 */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("目录已被删除!");
  }}

以上代码运行输出结果为:

目录已被删除!
