1) Start by writing your package:
mypackage\Main.java:
2) write a manifest file:
Manifest.mf:
3) package everything up in a JAR file:
jar cfm Main.jar Manifest.mf mypackage/*.class
4) as we have included the Main-Class attribute in the manifest file, we can run it as follows:
java -jar Main.jar
outputs:
