When using Java, you often encounter Resource Initialization or generating temporary files when the program starts. When the program exits, you need to clear these temporary files, or execute other necessary operations when the program exits. If the program Exits normally through the close/exit button provided by us, everything is fine, but if the user closes the window for running the virtual machine directly, everything will become more complicated.Fortunately, Java provides an elegant way to
How to force users to fill in log information when submitting SVN?
If you are using the tortoisesvn client, you can add the "tsvn: logminsize" attribute to the folder. When you use tsvn to submit changes in this folder, if the length of the log information is insufficient, the submit OK button will remain unavailable. However, this method is ineffective for non-tsvn clients.
As a more restrictive restriction, You can forcibly enter the log information on the Subversion server. In this case, you

Hook mechanism is the hook mechanism, which is implemented by table-driven, commonly used to deal with a variety of special cases. We have predefined hooks to fit some special events in the usual code logic, which allows us to have a lot less if else statements.Give an example of a college entrance examination, such as won the National first prize plus 20 points, second prize plus 10 points, third prize plu
