ObjectiveToday is the first day of 51 holidays, it should be happy to play the day, but as a north drift to the capital of the developers, it is difficult to go out to play. The place of fun is far, near and feel boring. So, idle write an article, summed up the program written yesterday.Yesterday afternoon my friend talked to me, he said there is a need to put the TXT file on the G read to write to the database. Using normal IO Results is naturally oo

For file reading and writing, of course, text file is best read, best written, no document structure to consider. For Windows Excel files such as the operation is not so easy, we can search, basically are all complex ways to read and write. Of course, this is not my original, in some csdn corner also have this article similar expression, we do not have to be ser

Recently looking at Brian Goetz's When I saw the 34th chapter, I suddenly thought of multithreading read-write files, and encountered some problems in the book1, how to ensure the security of the composite object?2, how to judge the constraint condition of invariance3, how do I synchronize with the Synchronized keyword and the lock?Here is a piece of code that reads data from source and writes it to the tar

ArticleID = 167 Read text files in various formats in j2s During the development of j2s, we often save a text information in a TXT text file as a resource. this facilitates modification and management. reading them will be difficult for some friends who have just started to get started with j2s. A few days ago I studied and

Common functions for php to read local files. Below, we use the. txt file as an example to introduce the function for php to read local files. we can use fopen or file_get_contents to read files, file_get_contents is simpler, and

We usually need to store large files such as audio and video on our mobile phones. We have learned how to store files (using File Operations) before. Considering the small storage space of mobile phones, at this time, we need to store the files in SDcard. Today we have learned how to store sdcard in android; First, if you want to use sdcard for storage in the pro

The Android resource files can be roughly divided into two categories: The first is a compiled resource file stored in the Res directory: This resource file system will automatically generate the ID of the resource file in R.java, so it is simpler to access this resource file, through R.xxx.id; The second is the native resource files stored in the assets directory: Because the system does not compile as

Usually we need to store large files on the phone like audio, video and so on, previously learned to use file for storage (using file operation to store); Due to the small storage space of the phone itself, this time we need to store the files in the SDcard, and today we also learned a bit on Android The method of storing and using SDcard;First, if you want to use SDcard for storage in your program, we have
