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

You can not call any method from terminal or cmd of any class.

You can execute class through terminal.

If your jar is executable try: java -jar "Name of your Jar"

Or set the class path of your jar: java -classpath path-to-jar <package>.<classname>

Answer 2

java -cp path/to/jar <package>.<classname>

example:

java -cp test.jar org.dekz.HelloWorld
