A **JAR** file is simply the compressed version of Java class files and all the subsidiary resources like (image files, audio files, etc.). It is more of an archived package file that can be unarchived very easily using any tool (e.g., WinZip). JARs have the `jar` extension.

> Remember: All Java files (`*java`) are usually converted into a single `jar` file.
