What ZIP and JAR files are
ZIP
ZIP is the most widely used archive format for compressing and bundling multiple files into a single container. It supports lossless compression and is natively supported by all major operating systems.
JAR
JAR (Java Archive) is a package file format based on ZIP that bundles Java class files, metadata, and resources into a single distributable file for Java applications and libraries.
