array=list.toArray(array); 1. 以上代码将集合list的内容放入数组array中,并将其赋值给array变量。这样,我们就成功地将集合内容放到了数组中。 完整代码示例 下面是完整的代码示例,将以上步骤整合在一起: AI检测代码解析 importjava.util.ArrayList;importjava.util.List;publicclassCollectionToArrayExample{publicstat...
类图是系统分析和设计阶段的重要产物,是系统编码和测试的重要模型。 类图的表示法 类的表示方式 在UML类图中,类使用包含类名、属性(field)和方法(method),且带有分割线的矩形来表示。 属性/方法前的加减号表示可见性 +:表示public -:表示private #:表示protected ...
clause exits by falling out the bottom. However, if the finally block creates its own reason to leave by executing a control flow statement (such as break or return) or by throwing an exception, that reason supersedes the original one, and the original reason is forgotten. For example, ...
