What is a .JAR file?
JAR files are archives that store executable programs or program libraries written in Java. The files can be executed on any operating system with the Java Runtime Environment (JRE) installed. JAR files are compressed archives that contain program resources, which may include CLASS files and a manifest file.
You may encounter JAR files when downloading programs that are written in the Java programming language. If you want to run a JAR program, you will need to install JRE on your computer.
