hi!!!

Normally a Java application consists of quite a bit of classes. Each public
class is stored in its own file. You don't want to carry all those files around
for every single deployment of your application do you? A .jar file is simply
a .zip file with a bit of additional information for the JVM; it's quite convenient:
just one file to take care of instead of an entire bunch of .class files.

kind regards,

Jos

It's not like a package as a Java package; it is a collection of .class files and
resource files. Physically it's a .zip file.

how to create a .jar file?.....
You have to use the 'jar' command or possibly your IDE can do the job for you.

kind regards,

Jos
