What is JAR (file format)?
{{Infobox file format | name = JAR | icon = | extension = .jar | mime = application/java-archive | developer = Oracle Corporation | type = data compression | url = https://docs.oracle.com/javase/8/docs/technotes/guides/jar/jarGuide.html }} Java ARchive (JAR) is a file format created by the [[Oracle Corporation]] that is based on the [[ZIP (file format)|ZIP]] [[file format]]. The primary motivation for the creation of JAR was to allow Java [[Applet|applets]] and their files to download using a single [[Hypertext Transfer Protocol|HTTP]] connection instead of a new connection for each piece. <ref>{{cite web|title=JAR File Overview|url=https://docs.oracle.com/javase/8/docs/technotes/guides/jar/jarGuide.html|access-date=2021-02-12|website=docs.oracle.com}}</ref> This allows webpages to load faster and the applet can begin functioning. == Usage == JAR files use the file extension .jar and the MIME media type <code>application/java-archive</code>. JAR files are packaged with the ZIP file format, and they are used for data compression, archiving, decompression, and archive unpacking. <ref>{{cite web|title=Using JAR Files: The Basics (The Java™ Tutorials > Deployment > Packaging Programs in JAR Files)|url=https://docs.oracle.com/javase/tutorial/deployment/jar/basicsindex.html|access-date=2021-02-12|website=docs.oracle.com}}</ref> == References == <references /> [[Category:Computer file formats]]
