Sorry for the really bad title but I have no idea how to explain it without an example.
My problem is that I need to write a program that will do its operation on a number that is inputted when the program and class is opened.
For example a program that have a class that multiples a number by 3 would be "java program.multiply(3)" in the command line. How am i able to take the input of 3 when its wrote with the command to open the program?
And again sorry for the bad explanation I'm having a really hard time explaining it considering its quite simple
