library(库) contains procedures that may be used in creating new programs.
- function library
- class library
- Libraries improve code
reusability.
- Existing code segments can come from internal or external sources, such as libraries or previously written code.
- The use of libraries simplifies the task of creating complex programs.
Application program interfaces (API-应用程序编程接口) are specifications(规范) for how the procedures in a library behave and can be used.Documentation for an API/library is necessary in understanding the behaviors provided by the API/library and how to use them.
