Java枚举编程，附上李兴华老师视频教学的源代码，有需要的朋友可以下载来看看，Java文件(Java enum programming, accompanied Li Xinghua teacher teaching video source, a friend in need can be downloaded to see, Java file)

说明：  因为某些国家的进口管制限制，Java发布的运行环境包中的加解密有一定的限制。比如默认不允许256位密钥的AES加解密，解决方法就是修改策略文件。(Because of the restrictions of import control in some countries, there are some restrictions on the encryption and decryption in the operating environment package released by Java. For example, AES encryption and decryption of 256 bit key is not allowed by default. The solution is to modify the policy file.)

一个有jsp和servlet开发的网络购物系统(A jsp and servlet development of online shopping system)

java 连接阿里云的mqtt服务(客户端源码)

说明：  jsP过滤器模型，十分适合新手学习，建议下载，内容详细(JsP filter model, very suitable for beginners to learn, it is recommended to download, detailed content)

说明：  基本算法： 采用博弈比较常用的策略。 计算机下子前，分别对玩家和电脑棋型进行评估，然后根据棋型对每一位置打分（玩家和电脑在同一点的分数不同），比如活三100分，冲四1000分等，然后根据每个落子点分数进行选择。采用极大极小值策略，进行多步计算。(Basic algorithm: The game strategy is commonly used. Before computer playing, players and computer chess models are evaluated separately, and then each position is scored according to the chess pattern (players and computers have different scores at the same point), such as live three hundred points, go four thousand points, and then choose according to the score of each falling point. Multi-step calculation is carried out by using the minimax strategy.)

说明：  oints in data to the points in model. Fit with respect to minimize the sum of square

使用Java编写的国际象棋的源码,仅供大家灿烂靠(The source code for chess written in Java,It is only for everyone to be brilliant.)

说明：  一个应用线程实现指针运动的指针时钟程序。程序应用绘制函数时钟面板，根据线程休眠时间间隔，每隔1000ms进行一次重绘。程序通过获取系统时间函数并加以计算个指针位置，再利用绘制函数将其绘制在面板上，通过设置指针长度及颜色，实现时针、分针、秒针的区分。次外，通过获取窗体大小，设置圆面圆心坐标及半径，可依据窗口大小动态划分圆面大小，并动态绘制刻度点位置。(A pointer clock program that uses threads to implement pointer movement. The program draws the function clock panel and redraws it every 1000ms according to the interval of thread dormancy. The program obtains the system time function and calculates the position of a pointer, then draws it on the panel by drawing function. By setting the length and color of the pointer, it achieves the distinction of clockwise, minute and secondhand. Secondly, by acquiring the size of the form and setting the coordinates and radius of the circle center, the circle size can be dynamically divided according to the size of the window, and the location of the scale points can be dynamically plotted.)
