course not, think about serialization can make it easy for us to touch the object's private data domain, this is how dangerous loophole! To summarize, there are four types of class objects in the JDK that are absolutely not serializable.(1) Classes that are too dependent on the underlying implementation (too closely tied to native code). Like Java.util.zip.Deflater.(2) The state of an object depends on the inside of the virtual machine and the constantly changing runtime environment. Like Java.

How to Use Python to compress and decompress zip files This article mainly introduces how to use Python to compress and decompress zip files. It mainly uses the zipfile package. For more information, see Python zipfile provides a very convenient way to compress and decompress zip files. For example, in the directory where The py script is located, there are the following files: The Code is as follows: Reada

(buffer, 0, readsize); downloadCount + = readsize; // obtain the downloaded size from time to time // increase by 1% if (updateCount = 0 | (downloadCount * 100/totalSize-down_step)> = updateCount) {updateCount + = down_step; sendMessage (DOWN_UPDATA, updateCount) ;}} if (httpURLConnection! = Null) {httpURLConnection. disconnect ();} tmp. renameTo (output); tmp = null;} catch (IOException e) {sendMessage (DOWN_ERROR, 0); throw new RuntimeException (e);} finally {try {if (tmp! = Null) {tmp. delet

Find these kinds of methods on the Internet, feel good, collect them, convenient for everyone to use JDK comes with the package java.util.zip.ZipOutputStream, shortcomings, file (folder) name with Chinese, garbled problem occurs, the implementation code is as follows /*** Function: Compress all files in SourceDir directory into zip format, save as specified zip file *@paramSourceDir If it is a directory, Eg:d:\\myeclipse\\first\\testfile, all files under the compressed directory; *

If we package multiple files and transfer them again, it will save a lot of computer resources. Here, I will show you how to read, decompress, and create ZIP files. Of course, here is a brief introduction. You need to implement the ZIP file in many details. For Ja

calculation, 1 for the current position as the origin. 2 means that the end of the file is calculated as the origin. Note that if the file is opened in a or a + mode, the file action tag is automatically returned to the end of the file each time the write operation is made. F.truncate ([size]) #把文件裁成规定的大小, the default is the location that is cropped to the current file action tag. When you read a file, Python remembers its location in the file, and if you still need to read from scratch for the

Python-specific databases in Python allow Python programmers to easily create a complete GUI with full function keys, this article provides the source code of the complete memory pool management program and test program for managing memory in a Python-specific database for your reference! Just like Python and wxWidgets, a specific Python database is also an open-source software with excellent cross-platform capabilities in Russia, supports running on 32-bit windows, most Unix or Unix-like system

When you open the file with the image browsing tool, you can see that the image is surrounded by a circle of single pixels, and the black pixel is that we use draw9patch. after we put the image in the Res/drawable folder and compile it on Android, decompress the APK package. You can see that although the Res/logs file is actually usableProgramTo simulate this process, you can directly import the .9.png image, and then automatically generate the edited .9.png image. Upload images, and finally D

Os.walk () function is passed in a string value, which is the path to a folder. You can have a forOs.walk () traverses the directory tree, returning 3 values:1. The name of the folder that is currently traversed;2. A list of subfolders in the current folder;3. The list of files in the current folder.Compression# New compressed file is opened in write mode, and write mode erases all the original contents in the zip file# The second argument passed in ' a ' is opened in Add mode, the file is adde

From a simple point of view, the ZIP format is a good choice, and Python's support for the ZIP format is simple enough to be useful. 1) Simple application If you just want to use Python for compression and decompression, then you don't have to go through the document, and here's a simple usage that you can see. Import ZipFile f = zipfile. ZipFile (' Filename.zi
