Jar files are important as it contains the class, image, and sound files for a Java application or applet gathered into a single file and possibly compressed. When a programmer gets a Java program development kit, a small program or utility called "jar" is included. The jar utility lets the programmer create, list, or extract the individual files from a JAR file.
