1: Introduction: The traditional real-time system is the domain of experienced experts, as they can handle a variety of custom kernels, nonstandard and mostly low-level languages, vendor-supplied custom I/O interfaces. This requires a new Java threading model to address this situation, which solves the four flaws that are currently embedded in the system in a timely manner: security, performance, portability. Program debugging time. Security is a comp

retrieve objects. This is the most important aspect of durability, because illegal SQL statements may reduce the speed of the database. This method also shields the application from the proprietary SQL statements that are chaotic throughout the application. The query language allows you to retrieve entities or objects and free developers from writing SQL SELECT statements.

garbage collection utilizes a feature known as the "weak generational hypothesis" (weak generational hypothesis), depending on the language in which the application is written, including the Java programming language:
Most objects that are allocated memory are not referenced (survived) too long, meaning that these objects are referenced for a short time

One of the great challenges we all face when writing unit tests is the dependency of modules on other components. Spending a lot of time and effort to configure a dependent component environment is a thankless task. Using mock is an efficient way to replace other components to continue our unit test build process. Next I'll show you an example of using a mock technique. Here I have a data access layer (DAL) to create a class that provides the basic API

Introduced
As a software developer and consultant who has worked for many years, I have seen a lot of different programming language code. There are both elegant and ugly, but unfortunately most of them are ugly. I want to be able to convince you, my development partners, that we should pay enough attention to our code style, especially those that provide user interface and other visual parts in the application. In the first part of the two-part serie
