Java中,这样算不算对抽象类进行创建对象实例化

已采纳

 abstract class Inter {
    public abstract void print();
    public abstract void run();
}

class Nonym {
    public static void main(String...args) {
        Inter i = new Inter() {
            public void print() {
                System.out.println("good");

实际上你是创建了Inter的子类，父类的类型指向了子类的实例，这事允许的。

你这种写法是创建了一个匿名内部类，实质是对抽象类创建了一个没有名字的子类，并重写了父类的方法，也就是说是对抽象类的子类对象创建了一个实例，不能算是对抽象类创建对象实例化

这样相当于创建了一个继承自Inter的子类的实例

你这个是新建了一个类，名字一样而已。

你这个不是实例化，只是实现的抽象类的方法。如果你把方法去掉，单独去NEW一个看看哈。

Logs Stacking
5年前

回答 2 已采纳 Description Daxinganling produces a lot of timber. Before loading onto trains, the timberjacks will place the logs to some place in the open air first. Looking from the sideway, the figure of a logs stack is as follows: We have known that the number of logs in each layer is fewer than the lower layer for at least one log, and that in each layer the logs are connected in a line. In the figure above, there are 12 logs in the bottom layer of the stack. Now, given the number of logs in the bottom layer, the timberjacks want to know how many possible figures there may be. Input The first line of input contains the number of test cases T (1 <= T <= 1000000). Then T lines follow. Every line only contains a number n (1 <= n <= 2000000000) representing the number of logs in the bottom layer. Output For each test case in the input, you should output the corresponding number of possible figures. Because the number may be very large, just output the number mod 10^5. Sample Input 4 1 2 3 5 Sample Output 1 2 5 34

Web服务期望参数为long int但在PHP中没有long int支持 php
8年前

回答 1 已采纳 I have to call a web service, which expects it's parameter to be of type long integer. I do not have access to the server logs, so I don't know why am I getting an error response from server. I am trying to send a parameter as string or float, but would a server automatically cast it in such a scenario? If not, how is it possible to call a web service needing long integer parameters with PHP? I was told by the administrator, that my calls contain a different session identifier (the parameter we re talking about) and that it is probably due to overflow of the integer type. Thanks!
Codeigniter中的Logs文件夹变得越来越重 php

回答 1 已采纳 I have enabled error logging in codeigniter and my logs folder path is application/logs/ in this folder files are being created from codeigniter automatically as log-2015-03-17.php and log-2015-03-16.php etc. I want that the files which are older than two days should be deleted automatically, so is there any way in codeigniter to do this or I have to create a cron for this purpose? Thanks in advance.
在JSON Web服务中验证和跟踪用户 php
12年前

回答 1 已采纳 I have contact management / CRM application used in-house by our company, It is a web based app and thus uses a lot of Ajax. Most of the data is JSON, and the backend server uses PHP with MySQL as the database... I would like to build a mini Adobe Air version of that, mostly because I can use Drag and Drop file uploads, client side image resizing, client side screenshot creation of uploaded files etc. etc. Now, because the server side is a glorified JSON data provider, I figure I can adapt it to provide data to the AIR app. My problem is, how do I handle authentication? In PHP I use sessions for authentication... For AIR i figure it will be more like a JSON webservice, where you call a certain URL to access certain JSON data. After a bit of brainstorming, here is what I came up with: The user logs in when the AIR app starts The server returns an unique token on successful login, and stores that token in the DB The AIR app has to append that token to every request it makes to the server On every request, the server checks the validity of the token by comparing it to the one stored in the DB. The questions are, is there a better way than this? How long should the token be valid for? How do i handle clients that close the application without logging out, and without giving me a chance to nullify the token on the server? If anyone has been in a similar situation, I hope to be enlightened by your answers... thanks
