 Java陷阱之assert关键字 一、概述 在C和C++语言中都有assert关键，表示断言。在Java中，同样也有assert关键字，表示断言，用法和含义都差不多。 二、语法 在Java中，assert关键字是从JAVA SE 1.4 引入的，为了避免和老版本的Java代码]]>https://blog.youkuaiyun.com/Janepen/article/details/5765857https://blog.youkuaiyun.com/Janepen/article/details/5765857JanepenMon, 26 Jul 2010 10:11:00 +0800    今天又看了一遍之前看过的装饰模式，这次看到的例子比上次看到的例子好多了，这次的例子很有说服力，大体的是说一个人要换不同的着装类型，一个很不错的例子，下面总结一下我对装饰模式的理解，何时使用装饰模式。
    装饰模式是是为己已有的功能到哪个态地添加更多功能的一种方式，当系统需要新功能的时候，要想旧类中添加新的代码，这些新的代码通常转世了原油类的核心职责或主要行为，
在主类中加入了新的字段，新的方法和新的逻辑，从而增加了主类复杂性的特殊行为的需要，而装饰模式且提供了一个]]>https://blog.youkuaiyun.com/Janepen/article/details/5758799https://blog.youkuaiyun.com/Janepen/article/details/5758799JanepenFri, 23 Jul 2010 20:48:00 +0800今天比较郁闷的，在Eclipse3.5中启动配置了Jboss5，但是启动的时候却出现了异常，不能启动，网上找了一节解决的方法都没有解决，后来用MyEclipse8就可以正常启动了。不知道那个高手能顾告诉我。。。13:57:54,828 ERROR [AbstractKernelController] Error installing to Instantiated: name=AttachmentStore state=Described
