Sprint Getting Started Building

针对于一些视频转码的工具类，工具类用到的转码工具分别是：ffmpeg、mencoder(For some video transcoding tools, the tools used in the tool class are ffmpeg and mencoder.)

Java 模式之抽象工厂，详细解答，值得一看(Java model abstraction factory, detailed answers, worth a visit)

R*树，具有添加，删除，查询节点功能，是搜索算法中的一种，常用于GIS软件中。(R* tree, with add, delete, query node function, is a search algorithm, commonly used in the GIS software.)

说明：  是一个基于java开发的拍卖系统 非常适合初学者看(Is a java-based development of auction system is ideal for beginners to see)

采用RSA公秘钥体制和MD5签名算法的安全通信(Using RSA public and secret key systems and signature algorithm MD5 secure communications)

说明：  飞机大战 首先对这个游戏分析,在屏幕上的物体都是飞行物,我们可以把建一个类,让其他飞行物继承这个类.游戏中应有英雄机(也就是自己控制的飞机)、敌人。而敌人应该分为打死给分的飞机（就是普通飞机），另一种就是打死有奖励的敌人。他们都应该是飞行物的子类，我们也可以为普通飞机和给奖励的敌人设一个接口让他们去实现接口，这样有利于以后的扩展，我在这里给的简化版的飞机大战，主要是为了让大家了解面向对象。(First of all, analyze the game. The objects on the screen are flying objects. We can build a class and let other flying objects inherit this class. There should be hero planes (i.e., planes controlled by ourselves) and enemies in the game. And the enemy should be divided into killing the aircraft (that is, ordinary aircraft), the other is to kill the enemy with reward. They should be subclasses of flying objects. We can also set an interface for ordinary aircraft and reward enemies to implement the interface, which is conducive to future expansion. The simplified version of aircraft War I gave here is mainly to let you understand object-oriented.)
