What is jmod files in Java?

JMOD files in Java are modular files that serve as a new packaging format for Java applications and libraries in the Java Platform Module System (JPMS). Introduced in Java 9, JMOD files encapsulate everything needed to run, install, and manage a module, including metadata and additional resources. Unlike JAR files, JMODs can include native libraries, configuration files, and other resources that are necessary for the module's operation.

JMOD files are particularly useful for distributing modules that include non-Java components, such as native code or resources. They ensure that all the necessary files are packaged together, allowing for easier management and deployment of modular applications.
