Convert JAVA to JAR

QUICK ANSWER
Is it possible to convert JAVA to JAR?
Yes - JAVA converts to JAR.

Real programs ship as a JAR: compile the .java files to .class, then package them with 'jar cfe app.jar MainClass *.class' (or let your IDE/Maven/Gradle build it). A JAR is a ZIP of compiled classes plus a manifest - you bundle classes, not the source.
