A JAR file is a Java archive format that contains a collection of multiple Java class files, resources, and the associated metadata, all into a single file, for sharing software or libraries on the Java platform.
JAR files have a specific .jar extension and are created in the ZIP format. Computer users can extract JAR files using any standard decompression software.
Moreover, to reduce the file size and achieving a better download time, the JAR format supports compression. Additionally, individual entries in a JAR file may be digitally signed by the applet author.
