ArrayList 使用数字来查找对象,因此在某种意义上讲,它是将数字和对象关联在一起。 map 允许我们使用一个对象来查找另一个对象,它也被称作关联数组(associative array),因为它将对象和其它对象关联在一起;或者称作字典(dictionary),因为可以使用一个键对象来查找值对象,就像在字典中使用单词查找定义一样。 Map 是强大...
The default value is 1 if the last allocated object was an instance, and 3 if it was an array. The following example shows how to set the number of loaded cache lines to 5: -XX:AllocatePrefetchLines=5 Only the Java HotSpot Server VM supports this option. -XX:AllocatePrefetchStepSize=...

2.3.1 Word文件采用jacob插件进行打印实现。 2.3.2 先将word转化为pdf文件,然后打印pdf(lz使用) 三、总结 一、Java的打印简介 在我们的实际工作中,经常需要实现打印功能。但由于历史原因,Java提供的打印功能一直都比较弱。实际上最初的 jdk 根本不支持打印,直到 jdk1.1 才引入了很轻量的打印支持。实际上,SUN 公...
What if you want to do more with your members' profiles than printing them out. Suppose that you want to validate the members' profiles or retrieve their contact information? In this case, you need a functional interface that contains an abstract method that returns a value. The Function<T,...
