I have summarized some of the string comprehension and usage in Java a long time ago, and finally realized some performance optimization of the string. The blog post is more about string storage. If you are interested, you can check the transfer connection. Tested in Taobao these two daysArticleI saw an article about Java string, talked about the efficiency of stringbuilder and stringbuffer, and found that I ignored the concept of capacity. For exampleCode: 1 stringbuffer

File and folder actions In this article we will learn about the files in Win 8 and the various actions of the folders. File actions in this article are mainly about: deleting files/moving files/copying files/renaming files Folder operation is divided into: Read folder/Create Folder/delete Folder/Rename folder First, all of the XAML code file sections are posted: Second, let's take a look at the CS code for deleting files/moving files/copying files/renaming files: Private async void Btnd

In the fallback n-Frame automatic Resend Request protocol, the size of the sending sliding window must be less than 2^m (M is the window's bit length, reason and so on), the receiving sliding window size is 1, below the protocol, the follow
