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 )
