complex operations on strings. Regular expressions were widely used in Perl at the earliest-as a tool for text processing, they made great contributions in the infancy of WWW. Later, in many languages, Regular expressions became part of the language as a standard library. For example, Microsoft's C # language contains a powerful Regular library (which is.. Net Framework library ). Boost. Regex gives C ++ programmers the ability to control regular expressions, so that they can easily deal with v

database. This method usually requires obtaining the record of the entire table from the database, because we cannot determine which sub-records the given primary key has, then, we can use recursion in programming code to obtain relevant subordinate records. This recursive method is usually difficult to avoid the endless loop problem caused by illegal records in the data (of course, you can also solve this problem, but it is a little troublesome and generally not elegant enough ). So can we sol
. You can use URL rewriting only when all pages that are part of a session are dynamically generated. The session ID cannot be hard-coded because it does not exist before running.
How to delete a session?
We certainly do not want the session to be retained, because the session object will occupy resources. The HTTP Protocol does not provide any mechanism for the server to know if the user has gone. How does the container know when the user will go? How can I know when the browser will crash? How

Change Notification Adapter
In the adapter, we have the items attribute, which is updated every time the adapter is automatically started.
1 var items: List by Delegates.observable(emptyList()) {2 _, _, _ -> notifyDataSetChanged()3 }
It simply sets the initial value and calls the defined function after each change.
In this case, I only call notifyDataSetChanged. However, as you can see, the new and old values received by the function, so technical

The famous open-source libraries ButterKnife, Dagger, and fit in Android are all implemented based on APT (Annotation Processing Tools. The core of the compilation annotation is APT. When we use APT to process annotations, the obtained elements are eventually converted into corresponding Element elements to obtain t
