答:UML定义了多种图形化的符号来描述软件系统部分或全部的静态结构和动态结构,包括:用例图(use case diagram)、类图(class diagram)、时序图(sequence diagram)、协作图(collaboration diagram)、状态图(statechart diagram)、活动图(activity diagram)、构件图(component diagram)、部署图(deployment diagram)等。在这些...
还有一种简单的方式,HashSet set = new HashSet(vector); 60、Collection 和 Collections的区别。 Collection是集合类的上级接口,继承与他的接口主要有Set 和List. Collections是针对集合类的一个帮助类,他提供一系列静态方法实现对各种集合的搜索、排序、线程安全化等操作。 61、Set里的元素是不能重复的,那么用什...
erDiagram ARRAYLIST { +String name +int size } LIST "1" -- "1..*" ARRAYLIST : contains ARRAYLIST --|> LIST : extends 总结 通过使用ArrayList和相关的方法,我们可以轻松地删除指定位置之后的所有元素。这种灵活性使得ArrayList在处理动态数据时非常有用。Java提供了强大的集合框架,使得数据操作变得高效而...
