supports the removal of elements through the iterator remove, Set.remove, RemoveAll, Retainall, and clear operations and removes the corresponding mappings from the map. It does not support add and addall operations. (3) set Returns a collection view of all mappings contained in a map clock. This collection is supported by the map, which is reflected in the collection and vice versa. When an iterator is traversing a collection, if the map is modified (except for the entry of the iterator itsel

into uppercase or lowercase.5. How to compare two strings?The comparable interface is implemented internally in String, with two comparison methods: CompareTo (String anotherstring) and Comparetoignorecase (String str). CompareTo (String anotherstring)Compares the passed-in anotherstring string, if it is less than the passed-in string, and returns a negative number if it is greater than the certificate. Returns 0 when two string values are equal. The Eqauls method returns true at this

example, a landing page, using the PO mode, will create a LoginPage class, the class will define the user name input box, password input box, login button webelenentFor the corresponding element to implement the corresponding method, the input box is used to input, you need to create a user name and enter the password method, so that the real page consistent, so the design concept is PO mode. The pagefactory belongs to the PO mode, which is used to initialize the page Class of each PO pattern i

execution.Surround notification is one of the most common types of notifications. Most interception-based AOP frameworks, such as Nanning and JBOSS4, provide only surround notifications.The concept of pointcut (pointcut) and connection point matching is the key to AOP, which makes AOP different from other old technologies that simply provide interception functionality.The pointcut enables the location notification (advice) to be independent of the OO hierarchy. For example, a around notificatio
