Title: Executing different methods in a Jar file
Post by: zscipio on April 01, 2009, 12:48:12 PM

A jar file has many methods in it.  When  I run the following: java -jar TheProgram.jar T     the main method in TheProgram is executed with a parameter of T.

Is there a way to execute one of the other methods in TheProgram.jar, say otherMethod(), by saying something like java -jar TheProgram.jar /otherMethod T?

Thank you.

Is this a homework assignment?
Basically a JAR is a compressed file that can have java applets.
Have you already read this page?

If you had, I don't understand your question. If a method is manifest yopur could use it, otherwise no.
But if the jar file is not locked, you can modify or extract what you want and put it into a new jar or some other form.
