How to call method in jar file with terminal?

Question

I have a compiled project in a jar file and I need to call a method from it.How can I do that in ubuntu terminal?

Answer 1

I need to call a method from it.

This is not very specific statement. if you are interested to call main method of your Main class then you can do

java -jar path/to/yourjar/yourJar.jar

• JAR Basics

if you want to call a method from this class from another class then you need to add this jar into your classpath and then you can access other methods. but since you wrote from terminal I assume the first approach fits for you
