What is .jar file extension?

JAR stands for Java Archive, associated primarily with Java by Sun Microsystems, Inc. Jar files are compressed files which are based on the ZIP file format and used by the Java Runtime Environment (JRE). JAR files can be created to store files in a similar manner as ZIP files. The JAR files contain several files which have been compacted into a single folder or one large file that has been compressed to achieve a practicable file size. The JAR format also supports compression which reduces the size of the file and improves download time. JAR is the only format which can handle audio, image as well as class files. It is also the only cross-platform archive format.
