: Hashtableobject.add (Key,value); Removes a Key/value key value pair in a hash table: Hashtableobject.remove (key); Remove all elements from the hash table: Hashtableobject.clear (); Determines whether a hash table contains a specific key key:HashtableObject.Contains (key); two ways to traverse a Hashtable object: Because each element of Hashtable is a key/value pair, the element type is neither the type of the key nor the type of the value, but the dictionaryentry type.

?Extends t> first of all, you can easily misunderstand the collection of all the classes that inherit from T, which is quite wrong, and I believe that you must have seen or used list 2. If you have Java programming ideas, see the generics chapter for a couple of sections. Use and distinction of wildcard characters. For example, to use a generic list, the elements of which are added to another list, you can use this way to prototype. public static

Some common performance issues are occasionally found in code reviews and recorded here.Demand We sometimes need to delay the deletion of the elements in the list Before optimization static void Removenullfor (int i = list. Count-1; I >= 0; i--)if (list[i] = = null)List. RemoveAt (i); O (N)} Since RemoveAt () is the operation of time, the entire function is. But this problem only takes time. After optimization You can do this simply by moving

The custom Dialog said that the activity's theme could be defined as Dialog style, making the activity look like a dialog box (Dialog), and custome title description if the title bar is customized. The dialog example also uses the dialog style to display the activity, and sets the icon for the titlebar. Dialogactivity uses the Android system-defined dialog Theme: Android:label= "@string/activity_dialog" Android:theme= "@android: Style/theme.dialog" &gt
