Nothing to write a small probe play, because only embedded in the blog and so on inside so this is only to get the user information, and so I later in writing a powerful probe.
The code is as follows:
String Agent = Request.getheader ("user-agent");StringTokenizer st = new StringTokenizer (Agent, ";");St.nexttoken ();Get the user's browser nameString Us
JavaScript works on the Web server side:1. The client requests data, that is, we enter a URL in the address bar while surfing the internet, and after the browser receives the data, the request message is sent to the remote Web server.The 2.web server responds to the request, the Web server finds the requested data, and sends the entire page containing the JavaScript script code as the corresponding content, which is sent back to the client machine.3. The client browser interprets and executes th

internally by the array, so access is faster, and the access speed is not affected as size increases, but when elements are added or removed, it is expensive to copy (reference) by moving the element or even creating a new array.The LinkedList is implemented internally by the linked list, and when size increases, the access speed is significantly affected, but the cost of deleting the element is less.Abstractset inherits from Abstractcollection and implements the set interface, all of the set i
container, and LinkedList implements the queue interface. The Priorityqueue implements the priority queue.The choice of seven listsAt the beginning of the article raised a question, the array implementation of the list is fast or the list of lists implemented by fast. Simulate a test:Publicstaticvoidadd () {longstart=0; longend=0;listAs you can see, the list of array implementations is faster than the linked list, regardless of the circumstances. When I set the initial size of the array to 10 m
scenarios are handled in the Makeiterator method, and only the EntrySet () method is required for the map type, for classes that implement the Iterable interface ( Collection is included), call iterator () to get the iterator object directly, for the enumeration type, with adapter enumerationiterator for adaptation, for arrays, Use array reflection to traverse the array into ArrayList, and for other types call the Arrays.aslist () method to create a list. Collectionutils also provides some othe
variable, not copy it.To achieve this effect, you can actually add a symbol before the variable:functionGetmoney () {$RMB= 1; $func=function() Use($RMB ) { Echo $RMB; //add 1 to the $RMB value. $RMB++; }; $func(); Echo $RMB;}Getmoney ();//Output://1//2OK, so the anonymous function can refer to the variables of the context. If the anonymous function is returned to the outside world, the anonymous function will save the variables referenced by the use, and the outside world will
child class instances might be affected by a property that has a reference type value on the prototype object (because the parent class's properties are all copied over on the subclass, the Parent property is overwritten). But in this way, subclasses extend inconvenient when we want to extend the parent class, such as when the parent class becomes a function Sup (a, B). So, here's an improved notation (the idea I've been told by an interviewer):Sup.apply (this, arguments);Second, Sub.prototype.

Type:The Dom1 class defines a node interface that will be implemented by all node types in the DOM. This node interface is implemented as a node type in JavaScript and can be accessed in all other browsers except IE. All nodes in JavaScript inherit from the node type, so all node types share the same basic properties and methods.Each node has a NodeType property that indicates the type of the node. The node type is represented by the following 12 numeric constants defined in the node type, and
