component The JAR file format offers many advantages and functionality, many of which are traditional compression formats such as ZIP or TAR that are not available. They include: security. You can digitally sign the contents of a JAR file. This way, a signature-aware tool can selectively grant you software security privileges, which cannot be done by other files, and it can also detect if the code has been tampered with. reduce download time. If an applet is bundled into a JAR
