    As a Java developer, you have likely come across JAR files and wondered what their purpose was. Here we explain what JARs are and how to open them - plus their contents!. JAR files (Java Archive Files) are a widely-used standard method of packaging and distributing applications. A JAR is composed of multiple files that make up its components necessary to run an application, such as CLASS files, images, sound clips and security certificates. JARs may be compressed further reducing file sizes while speeding download times; additionally each component in the JAR can be digitally signed to verify its origins. The JAR file format, developed to mirror its more familiar ZIP format, aggregates multiple files into one to facilitate download of an entire Java applet in one HTTP transaction rather than having each piece need separate connections requiring separate downloads. As such, JARs provide an efficient means of disseminating Java applications and library code. JAR files provide another effective method for packaging and distributing class libraries. A JAR file usually includes a manifest that lists all the files included within its archive and their paths; its contents can then easily be added to a Java program's classpath for any class calls made against that library.
