/**

		return fourdf.format(random.nextInt(10000));
	}

		// 生成随机数字并存入HashMap
		for (int i = 0; i < list.size(); i++) {

			int number = random.nextInt(100) + 1;

			hashMap.put(number, i);
		}

		// 从HashMap导入数组
		Object[] robjs = hashMap.values().toArray();

		ArrayList r = new ArrayList();

		// 遍历数组并打印数据
		for (int i = 0; i < n; i++) {
			r.add(list.get((int) robjs[i]));
			System.out.print(list.get((int) robjs[i]) + "\t");
		}
		System.out.print("\n");
		return r;
	}
}

        IAcsClient client = new DefaultAcsClient(profile);

        //设置相关固定的参数
        CommonRequest request = new CommonRequest();

        //设置发送相关的参数
        request.putQueryParameter("PhoneNumbers",phone); //手机号
        request.putQueryParameter("SignName","阿里云短信测试"); //申请阿里云 签名名称
        request.putQueryParameter("TemplateCode","SMS_154950909"); //申请阿里云 模板code
        request.putQueryParameter("TemplateParam", JSONObject.toJSONString(param));//验证码数据，转换json数据传递

        try {
            //最终发送
            CommonResponse response = client.getCommonResponse(request);
            boolean success = response.getHttpResponse().isSuccess();
