What is a .jar file?
JAR (Java Archive) is a ZIP-based package that bundles Java class files, resources, and a manifest into a single distributable unit. The manifest can declare an entry point and metadata, making the JAR executable or usable as a library. It is the standard packaging format for the Java ecosystem.
How to use this file
Use an example JAR to test ZIP-based extraction, manifest parsing, classpath and dependency tooling, and Java build or deployment pipelines.
