The structured life cycle method of software development divides the software life cycle into the planning phase, the development phase, and the operation phase.

Software life cycle, also known as software life cycle or system development life cycle, is the life cycle from software production to scrapping. During the cycle, there are problem definition, feasibility analysis, overall description, system design, coding, and debugging. and testing, acceptance and operation, maintenance and upgrade to abandonment and other stages. This time-based thinking method is an ideological principle in software engineering, that is, step-by-step and step-by-step advancement. Each stage must be defined, worked, and reviewed. , form documents for communication or reference to improve the quality of the software. However, as new object-oriented design methods and technologies mature, the guiding significance of software life cycle design methods is gradually decreasing.

Each cycle of the life cycle has certain tasks and produces documents (materials) of certain specifications, which are submitted to the next cycle as the basis for continuing work. According to the software life cycle, software development no longer only emphasizes "coding", but summarizes the entire process of software development. Software engineering requires that the start of each cycle of work can only be a continuation based on the "correct" results of the previous cycle; therefore, each cycle is a cycle of "activity-result-review-reactivity-until the result is correct" Progressing back and forth.

译者|陈峻审校|重楼上个世纪90年代,当人们提起软件编程时,通常意味着选择一个编辑器,将代码检入CVS或SVN代码库,然后将代码编译成可执行文件。与之对应的Eclipse和VisualStudio等集成开发环境(IDE)可以将编程、开发、文档、构建、测试、部署等步骤纳入到一个完整的软件开发生命周期(SDLC)中,从而提高了开发人员的工作效率。近年来,流行的云计算和DevSecOps自动化工具提升了开发者的综合能力,使得更多的企业能够更加轻松地开发、部署和维护软件应用。如今,生成式AI作为下一代开

线程的生命周期分几个阶段线程的生命周期分几个阶段Feb 21, 2023 pm 04:24 PM

5个阶段:1、新建,是刚使用new方法,new出来的线程;2、就绪,是调用的线程的start()方法后,这时候线程处于等待CPU分配资源阶段;3、运行,当就绪的线程被调度并获得CPU资源时,便进入运行状态;4、阻塞,在运行状态的时候,可能因为某些原因导致运行状态的线程变成了阻塞状态;5、销毁,线程正常执行完毕后或线程被提前强制性的终止或出现异常导致结束,那么线程就要被销毁。
