Description
A Static Library, typically denoted by the file extensions `.a` on Unix-like systems or `.lib` on Windows, is a collection of compiled object code modules that are linked into applications during the build process, rather than being loaded dynamically at runtime. This type of library contains a set of routines, external functions and variables, which are resolved and incorporated into the final executable file by a linker.
A JAR file is a Java archive (JAR) file used by the Java Runtime Environment (JRE), a framework used for executing Java programs. JAR files may serve as program libraries or as standalone programs that run if the JRE is installed on the computer or mobile device.
