Due to project requirements, it is necessary to convert the code developed by a Java project to the code of C # recently. It is time-consuming to convert the code of a file to a file. You can use the tool to add your own experience, you can get twice the result with half the effort. The following describes the conversi

Optimizing the memory usage of application code is not a new topic, but people usually don't understand it well. This article will briefly describe the memory usage of the Java process, and then delve into the memory usage of the Java code that you write. Finally, this article will demonstrate ways to improve the effic

While refactoring old code can be time-consuming, it's worth it, especially if all the tools that support refactoring now support Java code. There are a number of powerful tools for automatically refactoring Java cod

Surprisingly, there are only three ways to access XML data, if you're really curious. Yes-there are only three methods, one of which appears recently with a new Java API. This should be the case: a small selection makes it easier to choose the right approach for you. Callb

State machine programming ideas (2): Delete Code comments (currently C/C ++ and Java are supported), programming ideas javaPreface
Sometimes we need to delete comments to keep the information confidential or simply read the code.
I have considered regular expressions before, but it is quite troublesome to implement them. The state machine can classify multiple si
