关于target="_blank"去留的问题在网上已经被反复争议很多次了.有的说要留,有的说要去掉.主张留的一方主要是考虑到target="_blank"的属性目前来讲还没有一个好的方式来解决,而主张去的一方则拿出了rel与JS的解决方案. target="_blank"是否的存在是否有必要我想目前还有很多正处在一种盲区.我查阅了相关的文献,发现其实情况并非是我们所想的那样,事实上target="_blank"并非是不符合标准
java 1.5开始引入了注解和反射,正确的来说注解是反射的一部分,没有反射,注解无法正常使用,但离开注解,反射依旧可以使用,因此来说, 反射的定义应该包含注解才合理一些.当然,这只是个人想法,至于java官方为什么这么泾渭分明不得而知,最重要的是如何使用注解. 注解的功能分为2部分: 作为特定的标记 额外信息的载体 >>>>定义一个UserAnnotation注解类 @Target(value = { ElementType.FIELD }) @Retention(Retenti

Technorati 标记: java, 排序算法, 通配符 这几天无聊,又重新学起java的排序算法,为DualPivotQuickSort做准备.为了更好地适应各种情况,我们选择使用通用类型T和通配符的上下界来实现,同时这次谈的是对数组对象的排序.如果你对java 通配符的了解不深的,可以点击 这里 . 现在假设有如下排序方法: public static <T> void sort(T[] a, int n) 因为对象之间可以比较大小,数组对象必须是实现Comparable接口的.因此T
Technorati 标记: java, 泛型, generic java泛型应用是java核心基础之一,从java 5开始引进泛型.如果你曾经使用过java Collection,那你已经算是接触过泛型了.在java Collection里使用泛型是一件很简单的事情,可泛型还具有很多你意想不到的作用.在深入了解泛型之前,首先来了解一下泛型的一些基本概念与原理. 一.java 泛型引入 java泛型的应用可以提高的代码的复用性,同时泛型提供了类型检查,减少了数据的类型转换,同时保证了类型安全.下
