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.)

natural language query processing-abstract

An ListIterator is used to sequence over a List of objects. ListIterator can move backwards or forwards through the list.

使用Java+Ext技术，为小巧的HTMLArea 编辑器加上图片上传功能，因为以前的HTMLArea其它地方都很完美，就是没有图片上传功能，让喜欢她的人望而却步，现在好了，JAVA高手们运用手中的技术，结合目前流行的AJAX框架EXT技术，为她加入了一个插入图片并上传的功能(JAVA gurus use their technology use Java+Ext technology, plus the compact HTMLArea editor image upload feature, because the previous HTMLArea other place is perfect, is that there is no image upload feature, so that people like her flinch now combined with the popular AJAX framework EXT technology, she joined an insert pictures and upload)

Java软件设计，网络工程师，试卷，及其答案，很有用的，大家可以随意下在下来看(Java software design, network engineers, papers, and their answers, very useful, we can freely under the next term)

说明：  Java编程源代码，垂直滚动公告板，修改显示的文字。(Java programming source code, the vertical scrolling bulletin board, modify the display text.)

说明：  一个ＪＡＶＡ学习型ＢＢＳ，可以任意修改｀添加！如果您有任何意见或者建议请给我留言(a JAVA learning BBS, arbitrary changes can add `! If you have any comments or suggestions please give me a voice mail)

说明：  可以对pdf,doc,txt,html实现全文检索。用了中科院的ictloc分词器，分词效率较高(Can be pdf, doc, txt, html to achieve full-text search. With the Chinese Academy of Sciences of ictloc Word Breaker, efficient word)
