调用hbase的代码，可以进行动态创建表，查询修改删除记录。(Call the the hbase code can dynamically create tables, query modification delete records.)

本项目是一个倒计时动画和定位一体的小例子，实现了倒计时三、二、一、GO的动画效果和加载中等待动画效果和使用百度的locSDK_4.0.jar定位。另外还对多次点击请求只执行最后一次进行了处理。源码很简单有详细的注释编码GBK编译版本4.4.2(This project is a countdown animation and positioning of a small example, to achieve the countdown three, two, one, GO animation effects and load waiting for the animation effect and the use of Baidu s locSDK_4.0.jar positioning. In addition to repeatedly click request only the last time to perform the processing. Source code is very simple to have a detailed compilation of the notes GBK compiled version 4.4.2)

1. 分别使用Vector、Hashtable、Stack，ArrayList、LinkedList和HashSet作为容器类，实现以下要求： (1) 向容器中添加1,000,000个随机整数。 (2) 遍历容器中的所有元素。 (3) 随机产生100,000个整数，在容器中查找这些整数。 (4) 随机产生100个整数，从容器中删除这些整数。 (5) 统计完成以上各个操作需要的时间。 比较一下不同操作在不同数据结构下的性能差异。程序文件命名为Exe5_1.java。 (51 respectively using Vector, Hashtable, Stack, ArrayList, LinkedList and HashSet as the container class, to achieve the following requirements: ( 1) are added to the container 1000000 random integers. ( 2) to traverse all the elements in the container. ( 3) 100000 randomly generated integer, in the container to find these integers. ( 4) random produces 100 integers, is removed from the container of these integers. ( 5) complete the statistics above each operation requires time. Compare the different operating at different data structure performance differences. Program file named Exe5_1.java )
