Jar files are also zip files. simply zip will work.

Java Archive (JAR) files are compressed files into which you can store many files. If you place the many classes that your application, or applet need in a JAR file, you reduce the size of your distributabels.

To create a JAR file, go to the directory where your files are located and type:

 

jar -cf test.jar *.*

 

Thank you

i tried just as you mentioned
java test.jar indicated some class not found exception could not find
the main class
java -jar test.jar told me failed to load Main-Class manifest
attribute from test.jar
the folder in which i tried these has two classes J1.class and
J2.class and J1 is the main class
