A JAR file also contains additional metadata about the files it contains. However, if you treat the JAR file as an ordinary ZIP file, you can still see the metadata, by looking for the file META-INF/MANIFEST.MF in the unzipped JAR file.
The Java SDK provides the jar command. E.G. jar -tvf something.jar Displays the table of contents of the JAR file. However, a regular unzip command may run faster, and displays essentially the same thing. If you are writing a Java program, the JAR classes are usually just wrappers around the ZIP classes, to add easy access to the metadata.

Plain old unzip will work just fine. I have no idea why the Java designers thought they needed to create a new name-ending for an old storage type.
